SURFACE AREA:

The surface area is the area of the outside part of a shape. For a rectangular prism it would be the 2 sides, the top and bottom, and the front and back. A net is an easy way to show the rectangular prism's area .

The formula for this would be :

**surface area** = area top + area bottom + area side + area side² + area front + area back**OR**

**surface area**= 2(L x W) + 2(H x L) + 2(H x W)

= 2(4cm x 2cm) + 2(2cm x 4cm) + 2(2cm x 2cm)

= 2(8cm) + 2(8cm) + 2(4cm)

= 16cm² + 16cm² + 8cm²

= 40 cm²

You can use the formula examples i showed you here to help you answer your own surface area question.

VOLUME:

The volume is the measurement of how much space the shape takes up. The answer is always cubed or in an exponent ³.The volume of a rectangular prism would look like this.

The formula for this would be:

**volume =**L x W x H

= 3cm x 2cm x 2cm

= 12 cm³

**OR**

volume= area of base x height

volume

= 6cm² x 2cm

= 12cm³
