1. A cuboid had a volume of 120 cm. Its length is 8 cm and its breadth is 5 cm. Find the height if the cuboid. 5 cm 8 cm 2. The length of a rectangular block is 11 m and its height is 7 m. The volume of the block is 154 m”. Find its breadth. 7 m 11 m
1. Volume = length x breadth x height
120 cm³ = 8 x 5 x height
height = 120 ÷ (8 x 5)
= 120 ÷ 40 = 3
So, the height is 3 cm
2. Volume = length x breadth x height
154 cm³ = 11 × breadth × 7
breadth = 154 ÷ (11 x 7)
= 154 ÷ 77 = 2 cm
So, the breadth is 2 cm
3. height = Volume ÷ Area
= 144 liter ÷ 16 liter
= 9 cm
So, the height is 9 cm
