Why do you use square units to measure area?

When I find area, I find the number of unit squares I can tile an object with. The units that I use to measure are unit squares.

Jason says that the area of a rectangle that measures 5 in. by 10 in. is 50 in. Is he correct? Explain.

Jason is not correct. The area is 50 square inches, not 50 inches.

Write a word problem where you need to find the area of a rectangle to find the answer.

Marguerite is planning a garden. It is a rectangle with length 5 meters and width 3 meters. What is the area of her garden?

What is the area of a figure that is made up of a 3 cm by 4 cm rectangle and a 5 cm by 5 cm square? Explain your process.

The area is 37 square cm. I multiplied 3 times 4 to find that the area of the first rectangle is 12 square cm. I multiplied 5 times 5 to find that the area of the square is 25 cm. I added the two areas together to find the area of the figure.

What is the volume of a rectangular prism that has length 3 feet, width 2 feet and height 5 feet? Explain your process.

The volume is 30 cubic feet. I multiplied 3×2×5.

Why do you use cubic units to measure volume?

When I find volume, I find the number of unit cubes required to fill the object. The units that I use to measure are unit cubes.

Mio says that the volume of a box in the shape of a rectangular prism that measures 4 cm by 5 cm by 6 cm is 15 cm. Is she correct? Explain.

Mio is not correct. The volume of the box is 120 cubic cm. I think Mio added the measurements instead of multiplying, and used units instead of cubic units.

Write a word problem where you need to find the volume of a rectangular prism to find the answer.

Roberto has a fish tank in the shape of a rectangular prism that measures 2 feet by 3 feet by 2 feet. What is the volume of the fish tank?

What is the volume of a figure that is made up of two rectangular prisms? One rectangular prism has these dimensions: 7 cm by 2 cm by 3 cm. The other rectangular prism has these dimensions: 4 cm by 6 cm by 2 cm. Explain how you found the volume.

One rectangular prism has a volume of 7 × 2 × 3 = 42 cubic cm. The other rectangular prism has a volume of 4 × 6 × 2 = 48 cubic cm. I added 42 cubic cm and 48 cubic cm and found that the volume of the figure is 90 cubic cm.
