Question

Surface area of 12 inches x 5 inches x 8 inches

Answer 1

Put 12*5*8 into your calculator. The answer is 480 inches^3

Answer 2

Answer:

422 in²

Step-by-step explanation:

The surface area of a figure can be found using the general formula:

SA = 2ab + 2bc + 2ac, where 'a, b, c' are the side lengths of the object

Using the given dimensions, assign variables:

a = 12

b = 5

c = 8

Plug these into the equation:

SA = 2(12*5) + 2(5*8) + 2(12*8)

SA = 150 + 80 + 192 = 422 in²
