LOTS OF POINTS!!!!!!!!!!! >:)
Need to know if I am right and if someone can answer #2!!!

1. Find the volume of a cube with a side length of 4.5 feet.
My answer is- 91.13

2. Find the volume of the cube
One side is 3 1/8 inch
My answer- none

3.If the area of the face of a cube is 16 square meters, find the cube’s volume.
My answer-
lengthxwidthxheight which should be 4 m long, 4 m wide, 4 m high
so 4x4x4=64 m³ volume

4.Find the length of the side of a cube with a volume of 125 cubic inches.
My answer-
5x5x5=125 cubic inches
side length is 5 inches

5.If a cube is made of 8 unit cubes, what is the cube’s volume in cubic feet?
My answer-
8x8x8= 512
8ft³ = 512 cubic feet

6. Kero has a plastic container in the shape of a cube. The length of a side is 20 cm. She wants to fill it with 3 liters of water. Can her container hold this amount of water? Explain you answer. (1 liter = 1000cm3).
My answer-
20x20x20=8,000 cm³
8,000 cm^3=8 liters
3x1000= 3,000 cm³
3,000cm^3=3 liters
So the container can hold 8 liters so it wouldn't be a problem to hold 3 liters.

7.Janet has a cube with a volume of 294 cubic inches. Pat has a cube with a surface area of 216 square inches. Who has the bigger cube? Explain your answer.
My answer-
Janet's cube- 6.65³ =294 cubic inches
side length is 6.65
Pat's cube- 216÷6=36 square inches
one side face is 6 inches
Janet's cube is slightly larger than Pat's cube.

8. What is the difference between the surface area of a cube and the volume of a cube? Explain your answer by comparing the formulas for each measurement.
My answer-
Surface area is measured in square inches or square feet. Surface area is a flat area. Surface area is 2 dimensional; lengthxwidth

Volume is measured in cubic inches or feet (inchesxinchesxinches). Volume is the inside of an area. Volume is 3 dimensional; lengthxwidthxheight
