The figure shows a container ²₅ filled with water. The container is made up of two cuboids. The top cuboid has a square base of length 20 cm and height of 24 cm. The bottom cuboid has a square base of length 10 cm and height 14 cm. Find the height of the water level from the base of the container.
Volume of the top cuboid
= 20 x 20 x 24
= 9600 cm³ 

Volume of the bottom cuboid
= 10 x 10 x 14
= 1400 cm³ 

Total volume
= 9600 + 1400
= 11000 cm³ 

1 container = 11000 cm^3 
2₅ container = 11000 x ²₅ = 4400 cm³ 

Volume of water in the top cuboid
= 4400 - 1400
= 3000 cm³ 

Base Area of the top cuboid
= 20 x 20
= 400 cm² 

Height of water in the top cuboid
= 3000 ÷ 400
= 7.5 cm

Height of water from base
= 7.5 + 14
= 21.5 cm

Answer(s): 21.5 cm
