Question

A solid is 5 cm tall, 3 am wide, and 2 cm thick. It has a mass of 135 g. What is the solid's density?

Answer 1

Answer:

density of solid = 4.5 g/cm³

Explanation:

density = mass ÷ volume

• We know the mass of the object (135 g). We need to calculate the volume:

Volume = length × width × thickness

             = 5 cm × 3 cm × 2 cm

             = 30 cm³

• Now we can calculate the solid's density:

density = 135 g ÷ 30 cm³

            = 4.5 g/cm³
