Volume and Surface Area of a Rectangular Prism

Volume and Surface Area of a Rectangular Prism

by substitution

Volume = length x width x height

V = lwh

Multiple Choice

V = lwh

What is the value of V when l = 9, w = 6 and h = 5?

• 270

• 965

• 20

How did I do that?

• V = lwh

• V = l (times) w (times) h

• V = 9 x 6 x 5

• V = 270

Multiple Choice

V = lwh

What is the value of V when l = 6, w = 4 and h = 2?

• 642

• 48

• 12

How did I do that?

• V = lwh

• V = l (times) w (times) h

• V = 6 x 4 x 2

• V = 48

Multiple Choice

V = lwh

What is the value of V when l = 10, w = 4 and h = 3?

• 120

• 340

• 17

Multiple Choice

V = lwh

What is the value of V when l = 6, w = 4 and h = 5?

• 645

• 15

• 120

Surface Area = 2 x length x width + 2 x length x height + 2 x width x height

SA = 2lw + 2lh + 2wh

Multiple Choice

SA = 2lw + 2lh + 2wh

What is the value of SA when l=9, w=6 and h=5?

• 129

• 158

• 258

How did I do that?

• SA = 2lw + 2lh + 2wh

• SA = 2(9)(6) + 2(9)(5) + 2(6)(5)

• SA = 108 + 90 + 60

• SA = 258

Multiple Choice

SA = 2lw + 2lh + 2wh

What is the value of SA when l=6, w=4 and h=2?

• 88

• 24

• 44

How did I do that?

• SA = 2lw + 2lh + 2wh

• SA = 2(6)(4) + 2(6)(2) + 2(4)(2)

• SA = 48 + 24 + 16

• SA = 88

Multiple Choice

SA = 2lw + 2lh + 2wh

What is the value of SA when l=10, w=4 and h=3?

• 82

• 164

• 34

Multiple Choice
