Answer:
1,012.5 cubic units
Step-by-step explanation:
Vcube = s3
= (9 units)3
= 729 cubic units
Vtri. prism = (bhbase ÷ 2) • hprism
= (9 units • 7 units ÷ 2) • 9 units
= (31.5 square units) • 9 units
= 283.5 cubic units
Then, add the volumes.
729 cubic units + 283.5 cubic units = 1,012.5 cubic units
