Ali is baking a cake for her brother. She wants the cake to by 19 in. by 26 in. and 4
in. high. If she plans to frost the cake with
an icing that cost $0.02 per square inch of
coverage. How much will she spend on
icing?

$17.08

Step-by-step explanation:

Surface Area = (length)(width) + 2(length)(height) + 2(width)(height)

I am multiplying each of these by two because there is two of each shape. The exception is the (length)(width). You will only put icing on the top of the cake and not the bottom of the cake.

Surface Area = (19)(26) + 2(19)(4) + 2(26)(4)

= 494 + 152 + 208

= 854 square inches

Multiply by 0.02

854 x 0.02 = $17.08
