math is great by Brandon McGrew,Carla Lopez,Byron Couteeee

Formula

SA=6× a2

Examples #1

Example: Surface area of a cube with a side of length 4 = 4*4*6 = 96

Examples #2

Find the surface area if the length of one side is 3 cm

Surface area = 6 × a2

Surface area = 6 × 32

Surface area = 6 × 3 × 3

Surface area = 54 cm2


Examples #3

SA=6×a2

SA = 6 × (8)2

SA = 6 × (64)

SA = 384 cm2
