Volume of Prisms — Quiz

Question 3 • Grade 7 Mathematics

A triangular prism has a base that is 6 cm by 4 cm and a height of 8 cm. If all dimensions are tripled, what happens to the volume?

Answer
A
When the dimensions are tripled, the volume is eighteen times the original volume.
B
When the dimensions are tripled, the volume is three times the original volume.
C
When the dimensions are tripled, the volume is twenty-seven times the original volume.
D
When the dimensions are tripled, the volume is six times the original volume.

Explanation

Volume depends on three dimensions: the two dimensions of the triangular base and the prism’s height. Tripling each dimension multiplies the volume by 3 × 3 × 3 = 27. Therefore, the volume becomes twenty-seven times the original volume, as choice C states.
