Question

A side of a cube measures 4 centimeters and a side of a smaller cube measures 2 centimeters. the volume of the larger cube is how many times the volume of the smaller cube

a: 6
b: 2
c: 8
d: 4

Answer 1

C

Explanation:

Given the sides of cubes in the ratio a : b , then

ratio of volumes = a³ : b³

Here ratio of sides = 2 : 4 = 1 : 2 ( smaller : larger ) , so

ratio of volumes = 1³ : 2³ = 1 : 8

Then the volume of the larger cube is 8 times the volume of the smaller.
