Question

What is the volume of this object?

A)
24 mm3


B)
36 mm3


C)
48 mm3


D)
60 mm3

Answer 1

(A) 24
`mm^(3)`

Explanation:

Length of the first piece = 8 - 6 = 2 mm

Width of the first piece = 1 mm

Height of the first piece = 6 mm

Volume of the first piece = 2 × 1 × 6= 12
`mm^(3)`

Length of the second piece = 6 mm

Width of the second piece = 1 mm

Height of the second piece = 6 - 4 = 2 mm

Volume of the first piece = 6 × 1 × 2= 12
`mm^(3)`

Volume of the entire solid = 12 + 12 = 24
`mm^(3)`
