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
