So i need with this with the work cause i think i know but i want to make sure i am right by someone showing me then i can compare my idea plz

The amount of water that will fill the tank is the volume. To find the volume multiply the length by the width by the height.

20.25 x 10.5 x 12.5= 2657.8125
The volume is 2657.8125 in.³.

The amount of wrapping paper would be represented by the surface area.

20.25 x 10.5 = 212.625
12.5 x 10.5=131.25
20.25 x 12.5 =253.125
At least together to get 597 in.². Then multiply this by two because there are 6 faces.

597 ft.² x 2= 1194 ft.².

2a. To find the new dimensions multiply each dimension by 8.

The new dimensions would be 162 inches, 100 inches, and 84 inches.

b. The volume would be 8×8×8 = 512 times greater. Multiplied by eight for each dimension.

C. The service area would be 8×8 = 64 times greater. Multiply by eight for each of the two dimensions represented in the area.
