What is the surface area of a rectangular prism that is 15 centimeters long, 13 centimeters wide, and 8 centimeters high

Answer 1

I think it might be 1,560 is that right I multiplied 15 13 and 8 because you know LXWXH

Answer 2

S = 2(lw + lh + wh)
S = 2((15x13)+(15x8)+(13x8))
S = 2(195+120+104)
S = 838 cm^2
