Answer:
The total surface area of a rectangular prism is 310 inches
Step-by-step explanation:
The surface area of rectangular prism can be found using formula
Surface Area = 2(lw+hl+hw)
Where l = length
h = height
w = width
We are given:
l = 4
h = 5
w = 15
Putting values in the formula:
Surface Area = 2(lw+hl+hw)
Surface Area = 2((4*15)+(5*4)+(5*15))
Surface Area = 2(60+20+75)
Surface Area = 2(155)
Surface Area = 310 inches
So, The total surface area of a rectangular prism is 310 inches
