A net is a pattern made when the surface of a three-dimensional figure or solid is laid out flat showing each face of the figure. It is then possible to use the net to calculate the surface area of the solid.
Surface Area of a Cube using Nets
A cube is a three-dimensional figure with six matching square faces.
100% - 20% = 80%
$26.95 * 80% = $21.56
You multiply by 80% because you are taking 20% off and now want to know what 80% of the price will be.
Yes Clare should switch because $96 + 12% is $107.52 but if she get the other one, it would be $105 in one year because $8.75 x 12 is $105
