# Lesson 12

Volume of Right Prisms

Let’s look at volumes of prisms.

### Problem 1

1. Select all the prisms.
2. For each prism, shade one of its bases.

### Problem 2

The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area of a trapezoidal base of each prism?

### Problem 3

Two angles are complementary. One has a measure of 19 degrees. What is the measure of the other?

(From Unit 7, Lesson 2.)

### Problem 4

Two angles are supplementary. One has a measure that is twice as large as the other. Find the two angle measures.

(From Unit 7, Lesson 2.)

### Problem 5

Match each expression in the first list with an equivalent expression from the second list.

(From Unit 6, Lesson 22.)

### Problem 6

Clare paid 50% more for her notebook than Priya paid for hers. Priya paid $$x$$ for her notebook and Clare paid $$y$$ dollars for hers. Write an equation that represents the relationship between $$y$$ and $$x$$.

(From Unit 4, Lesson 8.)
