Question

A bar of lead is in the shape of a rectangular prism 2 cm by 3 cm

by 4 cm. The density of lead is 11.34 grams per cubic centimeter.
Find the mass of the bar of lead. *
272.16 grams
227.61 grams
262.17 grams

Answer 1

Explanation:

V = L * W * H

L = 4

W = 3

H = 2

V = 4 * 3 * 2

V = 24

Density = mass / Volume

density = 11.34

volume = 24

mass = ?

11.34 = mass / 24 Multiply both sides by 24

11.34 * 24 = 24 * mass /24

mass = 272.16 grams
