Answer:
158 in^2
Step-by-step explanation:
To determine the surface area of a rectangular prism, the Equation is:
Surface Area = (length x width + width x height + length height)x 2
The surface area with:
length of 2(5 x 3), a width of 2(5 x 8), a height of 2(3 x 8)
SA = 2(15) = 30, SA = 2(40) = 80, SA = 2(24)= 48,
SA = 30 + 80 + 48
SA = 158 square units.
SA = 2LW + 2LH + 2HW
SA = 2(5 x 3) + 2(5 x 8) + 2(3 x 8)
SA = 2(15) + 2(40) + 2(24)
SA = 30 + 80 + 48
SA = 158 in^2
So, your answer is: 158 in^2
