Question:
Volume of a rectangular box (cuboid) with length = 2ab, breadth = 3ac and height = 2ac is
(a) 12a3bc2
(b) 12a3bc
(c) 12a2bc
(d) 2ab +3ac + 2ac
Solution:
(a) 12a3bc2
We know that, volume of cuboid = length × breadth × height
Given, length = 2ab, breadth = 3ac, height = 2ac
= 2ab × 3ac × 2ac
= (2 × 3 × 2) × ab × ac × ac
= 12a3bc2
