Question

# If the area of a rectangle of length = 3 m and width = 7 m is 21m2, then what is the volume of a rectangular block having length = 3 m, width = 7 m and height = 1 m? 21 m3 22 m3 31 m3 23 m3

Solution

## The correct option is A 21 m3 Since the length and width of both the rectangle and the rectangular block are the same, we can get the volume by multiplying area with height. Volume (V) = area×height Volume (V) = 21×1=21 m3
