The diagram shows a tank made of some identical sections. Figure Q shows one section of the tank. When 5984 cm³ of water was poured into the tank, find the water level in the tank.
Volume of the bigger cuboid in Figure Q
= 32 x 10 x 3
= 960 cm³

Volume of the smaller cuboid in Figure Q
= 12 x 10 x 3
= 360 cm³

Volume of the Figure Q
= 960 + 360
= 1320 cm³

Number of sections of the container
= 5984 ÷ 1320
= 4 r 704

704 cm³ is less than 960 cm³.  So, the water only fills up to part of a bigger cuboid.

Base area of the bigger cuboid
= 32 x 10
= 320 cm²

Height of water in the bigger cuboid of the Figure Q
= 704 ÷ 320
= 2.2 cm

Height of 4 sections of the container
= 4 x (3+3)
= 24

Height of the water level
= 24 + 2.2
= 26.2 cm

Answer(s): 26.2 cm
