Question

1. Find the surface area and volume of a

rectangular prism formed by the net below.
The length is 10 units, the width is 4 units, and
the height is 5 units.

Answer 1

Surface Area : 220

Volume : 200

Explanation:

Use the formula 'surface area of a rectangular prism' : A = 2(wl+hl+hw)

• w - width - 4
• l - length - 10
• h - height - 5

A = 2( (4)(10) + (5)(10) + (5)(4) ) or just enter to a calculator and get 220

A = 2(40+50+20)

A = 2(110)

A = 220

Use the formula ' volume of a rectangular prism' : V = whl

• w - width - 4
• l - length - 10
• h - height - 5

V = (4)(5)(10) or just enter to a calculator and get 200

V = (20)(10)

V = 200
