Worksheet 2: I HAVE NO EYE DEER
Questions?
In this section we will answer…
◦ How do we find the area of prisms that have bases
OTHER THAN RECTANGLES?
◦ How do we find area of cylinders and parts of cylinders?
If B is the area of the base of a right prism and H is the height of the solid
V BH
If B is the area of the base of a prism and H is the height of the solid
Look for right angle!
V BH
REMEMBER:
The bases of a prism are always CONGRUENT AND PARALLEL!
The height of a prism is always the distance BETWEEN THE BASES!
1. Identify the BASE. Draw one, including all dimensions.
2. Find the area of that base using THE CORRECT AREA FORMULA.
3. Find the HEIGHT of the solid, and multiply it by the area you
found in Step 2. FINAL ANSWER (USE CUBIC UNITS!): _________________
