Expert: Chanda Walker - 3/24/2009


Question
Find the surface area of a box that measures 30 centimeters by 30 centimeters by 25 centimeters.

Please show the formula and provide the correct answer

Answer
h = 30
w = 30
d = 25

The area of the top and bottom (each) are:
w*d = 30*25=750

The area of the front and back (each) are:
h*w=30*30 = 900

The area of the left and right (each) are:
h*d=30*25=750


Summing all 6 surfaces together:

750 + 750 + 900 + 900 + 750 + 750 = 4800 cm^2
