The figure shows a tank ²₃ filled with water. The tank is made up of two cuboids. The top cuboid has a square base of length 24 cm and height of 31 cm. The bottom cuboid has a square base of length 12 cm and height 14 cm. Find the height of the water level from the base of the tank.
Volume of the top cuboid
= 24 x 24 x 31
= 17856 cm³ 

Volume of the bottom cuboid
= 12 x 12 x 14
= 2016 cm³ 

Total volume
= 17856 + 2016
= 19872 cm³ 

1 tank = 19872 cm^3 
2₃ tank = 19872 x ²₃ = 13248 cm³ 

Volume of water in the top cuboid
= 13248 - 2016
= 11232 cm³ 

Base Area of the top cuboid
= 24 x 24
= 576 cm² 

Height of water in the top cuboid
= 11232 ÷ 576
= 19.5 cm

Height of water from base
= 19.5 + 14
= 33.5 cm

Answer(s): 33.5 cm
