2. A cuboid has a volume of 7200cm3,square and a length of 32cm.Gind the length of the square face

Jawaban:

Remember the surface area is the total area of all the faces of a 3D shape.

The lateral surface area of a cuboid is given by:

LSA = 2 (lh + wh) = 2 h (l + w)

Example 1: Find the total surface area of a cuboid with dimensions 8 cm by 6 cm by 5 cm.

TSA = 2 (lw + wh + hl)

TSA = 2 (8*6 + 6*5 + 5*8)

TSA = 2 (48 + 30 + 40)

TSA = 236

So, the total surface area of this cuboid is 236 cm2.

Example 2: Find the surface area of a cuboid of dimensions 4.8 cm, 3.4 cm and 7.2 cm.

Solution:

Area of Face 1: 4.8 × 7.2 = 34.56 cm²

Area of Face 2: 3.4 × 7.2 = 24.48 cm²

Area of Face 3: 4.8 × 3.4 = 16.32 cm²

Adding the area of these 3 faces gives 75.36 cm², since each face is duplicated on the opposite side, the total surface area of the cuboid will be:

TSA = 2 (75.36) = 150.72 cm²

Example 3: The length, width and height of a cuboid are 10cm, 8cm and 7cm respectively. Find the lateral surface area of a cuboid.

Solution:

Lateral surface area of cuboid is given by:

LSA = 2h(l+w)

where,

l = length = 10 cm

w = width = 8 cm

h = height = 7 cm

Insert these values into the formula we will get:

LSA = 2 ×7(10 + 8)

LSA = 14 × 18

LSA = 252 cm2

Example 4: The length, breadth and height of a cuboid are 16cm, 14cm and 10cm respectively. Find the total surface area of the cuboid.

Solution:

The total surface area of a cuboid is given by:

TSA = 2 (l*b + b*h + h*l)

Given that:

l = 16cm

b = 14cm

h = 10cm

Substituting the values in the equation we will get

TSA = 2 (16*4 + 14*10 + 10*16)

TSA = 2(224 + 140 + 160)

TSA = 2 * 524

TSA = 1048 cm2

Example 5: Given a cereal box whose length is 20 cm, height is 30 cm and width is 8 cm. Find the surface area of the box.

Solution:

To find the surface are of the box we need to find the area of each rectangular face and add them all up.

The area of the front face is: 20 x 30 = 600 cm2.

The area of the top face is: 20 x 8 = 160 cm2.

The area of the side face is: 8 x 30 = 240 cm2.

Now add these values together we will get: 600 + 160 + 240 = 1000 cm2.

And the total surface area is therefore 1000 x 2 = 2000 cm2.

Example 6: Find the surface area of a cuboid whose sides are 3cm by 6cm by 10cm.

Solution:

Surface area of the cuboid is given by:

TSA = 2 (16*4 + 14*10 + 10*16)

TSA = 2(3 x 6 + 6 x 10 + 3 x 10)

TSA = 2(18 + 60 + 30)

TSA = 216 cm2

5. A block has a length of 2√3 cm, a width of 3√2 cm, and a height of 1√3 cm. Then the length of the diagonal is .... *

Jawaban:

√33 cm

Penjelasan dengan langkah-langkah:

Length = Panjang

Width = Lebar

Height = Tinggi

Panjang diagonal ruangnya

= √(2√3)² + (3√2)² + (1√3)²

= √12 + 18 + 3

= √33 cm ✔

6. The cuboid has a length of 5cm , a width of 7cm and a height of 5cm . Count the total of the surface area

Jawab:

L = 2 × (p.l + p.t +l.t)

= 2 × (5 × 7 + 5 × 5 + 7 × 5)

= 2 × (35 + 25 + 35)

= 2 × 95

= 190 cm

11. If a rectangle has a perimeter of 28 meters and a width of 5 meters, find the length of the rectangle.

The length of the rectangle is 9 meters.

[tex]\\[/tex]

Pembahasan

(Explanation)

To find the length of the rectangle, we first need to know the formula of the perimeter of a rectangle, which is:

p = l + w + l + w or p = 2(l + w)

where:

l = length w = width

Since we know that the width of the rectangle is 5 meters and the formula of the perimeter of a rectangle is 2(l + w), we can find the length of the rectangle by using the formula as follows.

⇒ p = 2(l + w)

⇒ 28 = 2(l + 5)

⇒ 28 = 2(l) + 2(5)

⇒ 28 = 2l + 10

⇒ -2l = -28 + 10

⇒ -2l = -18

⇒ l = -18/-2

⇒ l = 9

Hence the length of the rectangle is 9 meters.

12. A steel bar has length of 3 × 10² m, heated from 20°C to 120°C. If the length coefficient expansion is 1,2 × 10^-5 / °C and the length of steel to be affected by the first length, temperature changing and length linear coefficient expansion. Calculate the length of the end of the steel!

Materi: Pemuaian <<<<<<<<<Lo = 3 x 10² m
Δt = 120°C - 20°C = 100°C
α = 1,2 x 10⁻⁵/°C
Lt = ... ?

Problem solving:
Lt = Lo (1 + α x Δt)
Lt = 3 x 10² (1 + 1,2 x 10⁻⁵ x 100)
Lt = 3 x 10² (1 + 1,2 x 10⁻³)
Lt = 3 x 10² (1 + 0,0012)
Lt = (3 x 10²)(1,0012)
Lt = 300,36 m

13. A cube of copper has a mass of 600kg. copper has a density of 9.3g/cm³. Calculate the length of each side of the cube to the nearest mm.

19. A rectangle has a perimeter of 42 meters and a length of 13 meters. Find the width of the rectangle.

The width of the rectangle is 8 meters.

[tex]\\[/tex]

Pembahasan

(Explanation)

The formula of the perimeter of a rectangle is p =length + width + length + width.It can be simplified to p =2(length + width) or p = 2(l + w). As we know the length of the rectangle and the formula of the perimeter of a rectangle, we can use the formula to find the width of the rectangle as follows.

⇒ p = 2(l + w)

⇒ 42 = 2(13 + w)

⇒ 42 = 2(13) + 2(w)

⇒ 42 = 26 + 2w

⇒ -2w = 26 - 42

⇒ -2w = -16

⇒ w = -16/-2

⇒ w = 8

Therefore, the width of the rectangle is 8 meters.
