Basic mental arithmetic... 2 x 5 x 8 = 80cm3.
length times width
The new area is 22 = 4 times the original area. The new volume is 23 = 8 times the original volume.
a rectangle is 2-dimensional. basically, it's flat. it doesn't have volume. the area is length times width. if it was a rectangular prism, the volume would be length times width times height.
A rectangle does not have volume because it is 2 dimensional but it does have area which is length times width measured in square units.
If you multiply two measurements, you get only two dimensions - an area. For a volume, you need three dimensions.

Volume of a solid is proportional to the cube (3rd power) of its linear dimensions.When linear dimensions are doubled, volume increases by a factor of (2)3 = 8 times.
The volume of the rectangle is of no use to you, since the volume of every rectangleis zero. What you need to know is the rectangle's area and length.You're supposed to know that the area is the product of (length) times (height).So if you know the area and one of the dimensions, you can use that formula tofind the other dimension.

Without the dimensions, we won't be able to tell. The area of a rectangle is the length times the width. If those dimensions are in inches, the area will be in square inches.
A rectangle does not have volume because it is 2 dimensional but it does have area which is length times width measured in square units.
To find the volume of a solid object, you typically need to know the shape of the object. Common formulas for finding volume include V = lwh for a rectangular prism, V = πr^2h for a cylinder, and V = (4/3)πr^3 for a sphere. Once you have the dimensions of the object, plug them into the corresponding formula to calculate the volume.
If you multiply two measurements, you get only two dimensions - an area. For a volume, you need three dimensions.
The volume of any rectilinear solid can be found by multiplying the length times the width times the height. In this case, lx w x h = 15' x 12' x 3' = 540 cubic feet.
When you triple the dimensions of a flat (2-dimensional) shape,the area increases by (3)2 = 9 times.When you triple the dimensions of a solid (3-dimensional) shape,the volume increases by (3)3 = 27 times.
