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.
In order to find the Area, you multiply BXH (XW) so when finding the missing measurement you do Area/B (or H).
All you have to do is find the area divide it by the base and then you get the height.
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)
