Question

Joyce says that the figure below made I cm cubes has a volume of 5 cubic centimeters explain her mistakes

Answer 1

see the explanation

Explanation:

The picture of the question in the attached figure

we know that

The volume of a cube is equal to

`V=b^3`

where

b is the length side of the cube

In this problem we ha a cubes with a length side equal to 1 cm

so

`b=1\ cm`

substitute

`V=(1)^3=1\ cm^3`

The volume of each cube is equal to one cubic centimeter

so

To find out the volume of the figure, multiply the number of cubes by 1 cm^3

Looking at the figure

The total number of cubes is 6

therefore

The total volume is

`6(1)=6\ cm^3`

Joyce's mistake was counting 5 cubes instead of 6 (there is one cube that is not in sight)
