1. Week 3: Volume
Mrs.Brown

2. Day 1: Volume of Rectangular Prisms
Formula: V=lwh Volume is always Measured in Cubic Measurements. (exponent of 3)

3. Examples with Fractions and D Decimals:
V=(4.5)(3.2(4.2)
V= 𝑐𝑚 3
V= 1 2 𝑥 1 2 𝑥 1 4
V= 𝑖𝑛 3

Worksheet
All practice work may be done with your partner and with a calculator.
If you are not behaving and focusing on the math, this privilege may be taken away by the teacher.

5. Day 2: Volume of Triangular Prism
Formula: V= ½ lwh
V= ½ (4)(6)(3.5)
42 𝑖𝑛 3

6. Example:
L=8
W=5
H=9
We do not need 10 to solve for the volume in this question.
V= ½ (8)(5)(9)
V= 180 𝑐𝑚 3

8. Day 3: Volume of a Pyramid
Rectangular Pyramid
Formula: V= 1/3 lwh

9. Volume of a Square Pyramid
Remember that the base will have the same length and width because it is a square.
What is the volume of a square pyramid in which the base has 4 in sides, and it is 12 in tall?
V= 1/3 (4)(4)(12)
= 1/3(192)
=64 𝑖𝑛 3

10. Volume of a Pyramid
Triangular Pyramid : Because of the base being a triangle, you have to multiply is by ½ as well. Formula: V= 1/3 (1/2) lwh V= 1/3(1/2)(12)(12)(8) 1/6(12)(12)(8) 2(12)(8) 192 𝑚 3

12. Day 4: Solving with Volume
Watch this video before you begin to review the overall concept of Volume:
When given the Volume and two dimensions, you can find the missing dimension.

13. Find the height. V= 192 𝑖𝑛 3 What is the height? 192=(8)(4)h 192=32h
