The figure shows a rectangular container with a square base of area 81 m
2. The area of the shaded face is 90 m
2.
- What is the height of the container?
- Sam filled 25 of the container with water. Find the volume of the water.
(a)
Length of the base of the container
= √81
= 9 m
Height of the container
= 90 ÷ 9
= 10 m
(b)
Volume of water = Base area x Height
Volume of water
=
25 x Base area x Height
=
25 x 81 x 10
= 324 m
3 Answer(s): (a) 10 m; (b) 324 m
