Question

You need to wrap a present that is in the shape of a rectangle prism. The present has a length of 5 inches, a width of 4.5 inches, and a height of 3.5 inches. Find the total surface area of the present.
111.5 in2

55.75 in2

95.75 in2

135 in2

Answer 1

A 111.5 IN 2 HOPE THIS HELPS YOU!  let me know.

Answer 2

The surface area is made up of six sides and the area is then just the sum of the areas of the six sides...

A=2xy+2xz+2yz

A=2(xy+xz+yz)  in this case:

A=2(5*4.5+5*3.5+4.5*3.5)

A=2(22.5+17.5+15.75)

A=2(55.75)

A=111.5 in^2
