ADDITIONAL QUESTIONS TO PRACTICE

Example 1: Rosie wanted to paint a glass cube that she bought at a garage sale. Find the area of the cube that Rosie has to paint with each side measuring 6 inches.

Example 2: What is the surface area of an ice cream cone if its radius is 7 centimeters and slant height is 9 centimeters?

Example 3:
Camila wants to present her mother with a nice book. She found an empty cardboard box in the store room and thoughtfully decorated it to use as a gift box for the book. But Camila is unsure whether the book which has the volume of 180 units 3${}^3$ will fit in the box or not. Can Camila fit the book in the box that has the dimensions of 10×6×5$10\times 6\times 5$?

Example 4:
If the volume of a prism is 36 meter3${}^3$ and the base area is 4 meter2${}^2$, then, what would be the height of the prism?
