Question

What is the density of a 60-gram pyramid with rectangular base 5 cm x 7 cm and height 9 cm?

Answer 1

0.571428571429 grams per cm³

Explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

= (1÷3)×(5×7)×9

= 105 cm³

Then

The density = mass/volume

= 60÷105

= 0.571428571429
