Question

Given below are the length, breadth and height of some cuboids. From these measures, find their volumes.

	Length	Breadth	Height
(1)	14 cm	12 cm	8 cm
(2)	20.5 cm	16 cm	10 cm
(3)	7.5 cm	5.2 cm	4.5 cm
(4)	1.4 cm	1.1 cm	0.6 cm
(5)	2.2 cm	1.5 cm	0.9 cm

Answer 1

(1) Length of the cuboid = 14 cm
Breadth of the cuboid = 12 cm
Height of the cuboid = 8 cm
Volume of the cuboid = length × breadth × height
= 14 × 12 × 8 cm³
= 1344 cm³

(2) Length of the cuboid = 20.5 cm
Breadth of the cuboid = 16 cm
Height of the cuboid = 10 cm
Volume of the cuboid = length × breadth × height
= 20.5 × 16 × 10 cm³
= 3280 cm³

(3) Length of the cuboid = 7.5 cm
Breadth of the cuboid = 5.2 cm
Height of the cuboid = 4.5 cm
Volume of the cuboid = length × breadth × height
= 7.5 × 5.2 × 4.5 cm³
= 175.5 cm³

(4) Length of the cuboid = 1.4 cm
Breadth of the cuboid = 1.1 cm
Height of the cuboid = 0.6 cm
Volume of the cuboid = length × breadth × height
= 1.4 × 1.1 × 0.6 cm³
= 0.924 cm³

(5) Length of the cuboid = 2.2 cm
Breadth of the cuboid = 1.5 cm
Height of the cuboid = 0.9 cm
Volume of the cuboid = length × breadth × height
= 2.2 × 1.5 × 0.9 cm³
= 2.97 cm³
