Answer 1

Answer: Option C

Given : height = 6 inches, length = 10 inches, width = 4 inches.

Find : The volume of the cardboard box to be painted.

Step-by-step explanation:

Here we will have to find the volume instead of surface area because the question states "cover the box" which includes the base area as well.

formula for volume :

length x breadth x height

Step 1 : substitute the values given

Step 2 : 10 x 4 x 6

answer = 240 inches

Conclusion : C is the correct option since it matches with our answer.
