Answer:

Surface Area: 310 square inches.

Step-by-step explanation:

There are two ways to do this:

A) Formula for Surface Area of a Rectangular Prism = 2 * ( l*w + w*h + h*l). Where l is length, w is width & h is height. Based on the question:

l = 10 inch

w = 5 inch

h = 7 inch

Surface Area = 2 * ( 10*5 + 5*7 + 7*10) = 310 square inches.

B) Formula for Area of Rectangle = l*w, where l is length & w is width.

Look at the picture, I have marked the corners O,P,Q,R,S,T,U,V,W,X,Y,Z

If we calculate the Area of each rectangle and add them all we will get the surface area automatically.

  • Area of PQRS = 10*7 = 70 square inches
  • Area of STUV = 7*5 = 35 square inches
  • Area of VWXY = (7+5)*10 = 120 square inches
  • Area of ORYZ = 7*5 = 35 square inches
  • Area of RSVY = 10*5 = 50 square inches

Now add them all = 70+35+120+35+50 = 310 square inches.
