The figure shows a container ⁴₅ filled with water. The container is made up of two cuboids. The top cuboid has a square base of length 32 cm and height of 22 cm. The bottom cuboid has a square base of length 8 cm and height 8 cm. Find the height of the water level from the base of the container.
Volume of the top cuboid
= 32 x 32 x 22
= 22528 cm³ 

Volume of the bottom cuboid
= 8 x 8 x 8
= 512 cm³ 

Total volume
= 22528 + 512
= 23040 cm³ 

1 container = 23040 cm^3 
4₅ container = 23040 x ⁴₅ = 18432 cm³ 

Volume of water in the top cuboid
= 18432 - 512
= 17920 cm³ 

Base Area of the top cuboid
= 32 x 32
= 1024 cm² 

Height of water in the top cuboid
= 17920 ÷ 1024
= 17.5 cm

Height of water from base
= 17.5 + 8
= 25.5 cm

Answer(s): 25.5 cm
