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

Solution

(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
