Answer:
28 units³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Al ( A is the area of end face and l is the length )
Here A = and l = , thus
V = × ( cancel 21 and 3 by 3 and 2 and 8 by 2 )
= × = 7 × 4 = 28 units³
The answer is 10 because 3x2 is 6 and 6 x 5 is 30 and 3 x 10 is 30
