5. The volume of a cuboid is 24 300 cm3. Its base area is 1350 cm2. Find its length when its height is 2/5 the length of the cuboid.
Answer: the length of the cuboid is 45 cm
based on the question, we can conclude that,
Cuboid Volume = 24 300 cm3
base area = 1350 cm2
height = 2/5 length
to find the length of the cuboid,
1. find the cuboid height
[tex]Volume = Base Area * Height\\Height = \frac{Volume }{Base Area} \\Height = \frac{24300 cm3}{1350 cm2} \\Height = 18 cm\\[/tex]
2. find the cuboid length
[tex]height = \frac{2}{5} * length\\length = \frac{5}{2} * height\\ length = \frac{5}{2} * 18 cm\\length = 45 cm\\[/tex]

19. 1. The shaded face of a cuboid is a square. The length of the cuboid is 25 cm and its volume is 4900 cm? Find the length of one side of the square face. 25 cm 2. The capacity of a rectangular container is 425 m². Its height is 17 m. The base of the container is a square. Find the length of a side of its base. 17 m ?
Jawab:
1) 14 cm
2) 5 cm
3) 17 cm
Penjelasan dengan langkah-langkah:
#1
It talks about the volume of the cuboid.
Do you remember how to find the volume of the cuboid?
Here is the formula:
Vol = area of the base x length of the cuboid
volume = 4900 cm³
area of the base = ?
length of the cuboid = 25
With this formula, we can find the area of the base (the shaded area).
Vol = area of the base x length of the cuboid
4900 = area of the base x 25
area of the base = 4900 : 25
area of the base = 196 cm²
Note that we are asked to find the length of one side of the square. It means we need to find the square root of the area of the base.
area of a square = side x side
side = square root of the area
side = √196
side = 14 cm
#2
This problem is similar to #1, so to find the length of a side of its base we use the same way as #1.
Here is the formula:
Vol = area of the base x length of the cuboid
volume = 425 cm³
area of the base = ?
length of the cuboid = 17
With this formula, we can find the area of the base (the shaded area).
Vol = area of the base x length of the rectangular container
425 = area of the base x 17
area of the base = 425 : 17
area of the base = 25 cm²
Now we need to find the square root of the area of the base.
area of a square = side x side
side = square root of the area
side = √25
side = 5 cm
#3
In this problem we see that we already know the cube's volume.
Do you remember how to find the cube's volume?
It actually has the same concept to the cuboid's volume that we should multiply the area of the base by the height. However, since all of the edges have the same length, we just need to multiply them three times.
Here's the formula how to find the cube's volume:
Vol = edge x edge x edge
Volume = 4913 cm³
edge = ?
We can write the formula like this:
Vol = edge³
4913 = edge³
edge = ∛4913
edge = 17 cm
Hope this explanation can help you.

20. the base face of a prism is a regular hexagon. the height of the prism is 25 cm and the total area of the triangles serving as the lateral faces is 3000 cm^2. find:a. the length of each of the base edgeb. the volume of the prism
a.
luas = k x t
3000 = k x 25
3000/25 = k
120 = k
sisi segi 6
the length of each of the base edge= 120 : 6
= 20
b. La = s² x 3/2 √3
= 20² x 3/2 √3
= 400 x 3/2 √3
= 200 x 3√3
= 600√3
volume = La x t
= 600√3 x 25
= 15.000 cm³
