>** Surface Area of a Rectangular Prism** <

dimensional figure)

prism has 6 faces. The top and bottom is called

base.

Find the surface area of the Rectangular Prism below.

Surface area formula = 2 × l × w + 2 × l × h + 2 × w × h

Surface area = 2 × 11 × 5 + 2 × 11 × 6 + 2 × 5 × 6

Surface area = 110 + 132 + 60

**SA = 302 cm**

Surface area = 2 × 11 × 5 + 2 × 11 × 6 + 2 × 5 × 6

Surface area = 110 + 132 + 60

length 11 cm, width of 5 cm, and height 6 cm

Find the surface area of a rectangular prism with a length of 7

cm, a width of 4 cm, and a height of 2 cm

cm, a width of 4 cm, and a height of 2 cm

SA = 2 × l × w + 2 × l × h + 2 × w × h

SA = 2 × 7 × 4 + 2 × 7 × 2 + 2 × 4 × 2

SA = 56 + 28 + 16

**SA = 100 cm**

SA = 2 × 7 × 4 + 2 × 7 × 2 + 2 × 4 × 2

SA = 56 + 28 + 16
