Question

A boy found a solid metal box in his backyard. The box had been buried for so long, it was difficult to determine from what the box was made. The boy measured the box and found its volume (v) to be 17.63 cubic centimeters (cm3) and its mass (m) to be 158 grams (g). The boy knows the formula for density (D) is D = m/v. This table shows the density of several metals. DENSITY OF METALS *

A. copper
B. gold
C. silver
D. tin​

Answer 1

Box is made up of copper, because density is 8.96 g/cm³.

Step-by-step explanation:

Given data:

Volume of box = 17.63 cm³

Mass of box = 158 g

Which metal box is this = ?

Solution:

First we will calculate the density of box then we will compare it with the density value of given metals.

d = m/v

d = 158 g/ 17.63 cm³

d = 8.96 g/cm³

The calculated density is similar to the given density value of copper thus box is made up of copper.
