Ina makes cakes in a pan shaped like a rectangular prism. The base of the pan is an 8-inch by 12-inch rectangle, and the volume of the pan is 288 cubic inches. Find the surface area of a cheesecake baked in this pan.

Respuesta :

Answer:

328 in ²

Step-by-step explanation:

Ina makes a cake with volume

12 x 8 x H = 288 in ³.

96 x H =  288 in ³.

H = 288/96

H = 3

Surface Area

LW (2) = 96 x 2 = 192

LH (2) = 12 x 3 x 2 = 72

WH (2) = 8 x 4 x 2 = 64

192 + 72 + 64 = 328 in²
