EXAMPLE 1:
Find the perimeter for the shape below.
SOLUTION:
To find the perimeter, we have to find the number of sides and the length of a side. Number of sides: 10 Length of a side: 3 cm
Mathematic Equation:
\(10\times3\text{ cm} = 30\text{ cm}\)
EXAMPLE 2:
Find the volume of the object below.
Volume of the big cube \(=6\text{ cm}\times5\text{ cm}\times4\text{ cm}\) \(=120\text{ cm}^3\)
Volume of the hollow part \(=4\text{ cm}\times3\text{ cm}\times2\text{ cm}\) \(=24\text{ cm}^3\)
Volume of the object \(=120\text{ cm}^3-24\text{ cm}^3\) \(=96\text{ cm}^3\)
