Question

Three blocks are shown:

Block A has mass 3 kilograms, length 8 centimeters, height 2 centimeters, and width 1 centimeters. Block B has mass 4 kilograms, length 1 centimeters, height 8 centimeters, and width 2 centimeters. Block C has mass 4 kilograms, length 8 centimeters, height 1 centimeters, and width 2 centimeters.

Which statement is correct?

Block A has the greatest density.
Block B has the least density.
The density of Block A is equal to the density of Block B.
The density of Block B is equal to the density of Block C.

Answer 1

Block A has the greatest density

Answer 2

Answer: Block A has a volume of 8 cubic centimeters and a mass of 3 kilograms. Therefore, its density is 3/8 = 0.375 kilograms per cubic centimeter. Block B has a volume of 16 cubic centimeters and a mass of 4 kilograms. Therefore, its density is 4/16 = 0.25 kilograms per cubic centimeter. Block C has a volume of 16 cubic centimeters and a mass of 4 kilograms. Therefore, its density is 4/16 = 0.25 kilograms per cubic centimeter. Therefore, the statement “Block A has the greatest density” is correct.

Hope this helps! :)
