Question

How many additional unit cubes are required to form a complete rectangular prism here?

• A. 22
• B. 30
• C. 27
• D. 8

Answer 1

The correct option is A 22

Number of unit cubes along its length = 5
Number of unit cubes along its width = 2
Number of unit cubes along its height = 3
Volume of the prism
= $length\times width\times height$
= $5\times 2\times 3$ cu units
= 30 cu units
Therefore, number of unit cubes in a prism = 30
Number of unit prism more require = 30 - 8 = 22
