Volume and Surface Area
Notes
Review! Evaluate each expression given the replacement values.
1) 3𝑥𝑦 − 𝑦 when 𝑥 = 3 and 𝑦 = −2
2) 2𝑎2 𝑏 when 𝑎 = 4 and 𝑏 = 2
BIG IDEA #1: We can use the measurements of a rectangular prism (box) or a
cylinder (can) to tell us how much space is inside or outside the shape.
**We call the space INSIDE the shape _________________.
**We call the space OUTSIDE the shape ___________________________.
BIG IDEA #2: We use formulas to find volume and surface area. You will
always have access to these formulas to help! The formulas are…
So how do we USE these formulas to find the volume and surface area of
shapes? Turn over to find out!
Examples 1) Find the volume and surface area of the shape below:
2) Find the volume and surface area of the shape below:
Question: What if the problem shows you a cylinder and they give the
________________ (the distance ALL THE WAY across?)
Answer: Cut the number in ___________!
Example : Find the volume and surface area of the cylinder below:
