Question

Problem 6: The prism is made from metal, with a density of 6.6 grams per cm?. Calculate the mass of the prism.
7 mm
18 mm
35 mm
(round your answer to the nearest hundredth)

Answer 1

Answer:

the mass of the prism is 29.11 g

Explanation:

Given the dimensions of the prism as;

7 mm = 0.7 cm

18 mm = 1.8 cm

35 mm = 3.5 cm

volume of the prism = 0.7 cm  x   1.8 cm   x  3.5 cm

                                  = 4.41 cm³

density of the prism, ρ = 6.6 g/cm³

The mass of the prism is calculated as;

mass = density x volume

mass = 6.6 g/cm³   x  4.41 cm³

mass = 29.106 g

mass = 29.11 g

Therefore, the mass of the prism is 29.11 g
