Name: Date:

These are MSTAR-style questions written for this curriculum to rehearse the format. They are not official Maryland assessment items. MSTAR — Maryland's new state test, first given in spring 2027 — uses the same kinds of questions you see here: selected response, select-all, two-part evidence questions, and written responses.

Fill in the bubble next to the one best answer.

A16 cubic inches
B40 cubic inches
C120 cubic inches
D158 cubic inches

Part B

Answer Part A before Part B — Part B asks about your reasoning.

Which expression shows the same volume written as base area times height?

A2 × (8 × 5)
B(8 × 5) × 3
C(8 + 5) × 3
D8 × (5 + 3)

Question 8Select all that apply

Select ALL statements that correctly describe volume:

Mark the box next to EVERY answer that is true. More than one is correct.

AVolume is measured in cubic units.
BV = l × w × h for a rectangular prism.
CVolume can also be found as base area × height.
DVolume is measured in square units.
EDoubling only the height of a prism doubles its volume.

Part C — Show Your Thinking

Answer in writing, the way the state test's constructed responses work.

Question 9Written response · 2 points

A box needs to hold exactly 60 cubic inches. Give three different sets of whole-number dimensions that work. Which set would make the box closest to a cube shape? Why might that matter?
