The surface areas of three coterminous faces of a cuboid are 5 cm2, 16 cm2 and 20 cm2 respectively. Find the volume of the cuboid.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 40 cm3
We have given,
The surface areas of three coterminous faces of a cuboid are 5 cm2, 16 cm2 and 20 cm2 respectively.
Area of the cuboid = lbh
lb = 5
bh = 16
hl = 20
So,
lb × bh × hl = 5 × 16 × 20 =1600
(lbh)2 = 1600
lbh = 40 cm3
