Me find the surface area of these both

The formula to find surface area is SA= 2(L×W + L×H + H×W)

The 2 is there to double each side.

so..

A)

SA = 2(L×W + L×H + H×W)

= 2( 16×9 + 16×4 + 4×9)

= 2( 144 + 64 + 36)

= 2( 244)

= 488 units2

B) SA = 2(L×W + L×H + H×W)

= 2 ( 13×9 + 13×4 + 4×9)

=2 ( 117 + 52 + 36)

=2 ( 205)

SA= 410cm2

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
