Question 2.
Sunni’s bedroom has the dimensions of 11 ft by 10 ft by 10 ft. Her den has the same height but double the volume. Give two sets of the possible dimensions of the den and the volume of the den.
Answer:

Given, the dimensions of Sunni’s bedroom = 11 ft by 10 ft by 10 ft

Volume = 11 x 10 x 10
