Question

Two similar solids are shown A and B

A=3cm B=6cm
Solid A has a volume of 60cm cubed
Work out the volume of solid B

Answer 1

120 cm³

Explanation:

this is a ratio and proportion of two similar solids

vol A = 60 cm³ and A = 3cm

vol B = ? and B = 6 cm

60 = 3

B 6

do cross multiply:

3B = 60(6)

B = 120 cm³

therefore, the vo. of B is 120 cm³
