One edge of a cube is measured and found to be 13 cm. the volume of the cube in m3 is ________.
1 answer:
Since a cube is defined to have the same measurement in all three dimensions, it's volume can be calculated by raising the measurement of one side to the power of three.
In the problem we are given a measurement in centimeters and we are tasked to find the volume in m³. To make the calculation easier, we can just convert the measurement immediately since we know 100cm = 1m. Following this conversion, 13cm will be equal to 0.13m.
For the volume we'll get:
cubic meters or 
cubic meters if you are more comfortable expressing it in scientific notation.

First we must find area of a single square.
Meaning we divide total area of 80 centimetres squared by 5 since we have 5 squares in the shape.
Now from the picture we can see that the perimeter of shape is combined by 4 times 3 times the length of side of 1 square.
So we need to find side of 1 square.
As we stated before the formula for perimeter of this shape is:
The perimeter of shape is 48 centimetres.
Hope this helps.
