Question

This diagram represents a solid object with a mass of 120 grams. What is the density of the object?

Answer 1

Answer:

a. 30 cm³

b. 4.33 g/cm³

Explanation:

a Volume of the object = l*w*h

l = 5 cm

w = 2 cm

h = 3 cm

Volume of object = 5*2*3 = 30 cm³

b. Density of the object = mass of the object / its volume

Mass of object = 130 grams

Volume = 30 cm³

Density of the object = $\frac{mass}{volume} = \frac{130}{30} = 4.33 g/cm^3$
