Question

Identify the step where an error occurs for the first time while calculating the volume of the below given solid.

• A. Step 1: 8$\times$ 2 $\times$ 2 = 32 cu units
• B. Step 3: 32 cu units + 32 cu units = 64 cu units
• C. No error
• D. Step 2: 2 $\times$ 2 $\times$ 8 = 32 cu units

Answer 1

The correct option is D Step 2: 2 $\times$ 2 $\times$ 8 = 32 cu units


Step 1: We first calculate the volume of rect. prism 1.
Volume = 8 $\times$ 2 $\times$ 2 = 32 cu units

Step 2: We find the volume of rect. prism 2.
Volume = 2 $\times$ 2 $\times$ 6 = 24 cu units

Step 3: To find the volume of the solid, we add up the volumes of the prisms by which it is made of.

$\therefore$ Volume of the solid
= 32 cu units + 24 cu units
= 56 cu units
