If you know the Volume and the Height of the prism, then you can divide the volume by the height to get the base area. B=V/H
If you know the side lengths of the base then you could simply multiply them together to get the base area.
length times width
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
The volume of any right prism (the floor and ceiling are identical in shape) = Base area * heightSA = BA + LASA = BA + phLA=ph
The formula will depend on what it is that you are trying to find: the volume or the surface area.
All you have to do is find the area divide it by the base and then you get the height.
In order to find the Area, you multiply BXH (XW) so when finding the missing measurement you do Area/B (or H).
The base of a rectangular prism is a rectangle. The area of a rectangle is length times width.
Volume of rectangular prism = area of base x height
Multiply the base area by the height.
If the base is a rectangle, use the formula for the area of a rectangle.
Volume of a rectangular prism = base x height. If volume and height are known, solve for base area by dividing volume by height.
Multiply base area x height.
Multiply the base area by the height.
Volume = Base Area * Height So Height = Volume/Base Area
You can only find the area of the base with this information. The volume divided by the height will give you the area of the base.
Volume of a rectangular prism is equal to the base area x height. (V=BxH or Volume = Base Area * Height) To get the base area, simply divide the volume by the height. (B=V/H or Base Area = Volume / Height)
You find the area of the base and then find the area of one triangle. Multiply that one triangle by 4 and then add the base. The above is correct for a triangular pyramid NOT a triangilar prism. A triangular prism has two triangular ends and three rectangular faces. The rectangular faces need no be the same shape, but if they are, So Area = 2*area of triangular ends + 3*area of rectangular faces If not, you'll just have to calculate each area separately and add them.
surface area=(perimeter of base)x(height of the shape)+(area of the base)x(2)
