Rectangular Prism Calculator
A prism is defined as a 3dimensional solid object which has identical ends, flat faces, and the same crosssection all along its length. A rectangular prism is a threedimensional shape, having six faces, and all the faces of the prism are rectangles.

How to Find the Rectangular Prism Calculator?
The surface area of a rectangular prism is the number of unit squares that can be fit into it and it is measured in square units. The surface area of a rectangular prism is calculated using the formula:
The surface area of a rectangular prism = 2(lw + wh + lh)
Where 'l' is the length of the rectangular prism, 'w' is the width of the rectangular prism and 'h' is the height of the rectangular prism.
The volume of the rectangular prism is defined as the capacity of the rectangular prism or the measure of the amount of space it occupies and it is measured in cubic units. The volume of a rectangular prism is defined by multiplying the length, width, and height of the prism.
The volume of rectangular prism = (l × w × h)
Where 'l' is the length of the rectangular prism, 'w' is the width of the rectangular prism and 'h' is the height of the rectangular prism.
Let us now better understand the formulas to find the surface area and volume of a triangular prism by solving an example.
Solved Examples on Rectangular Prism Calculator

Example1:
Find the surface area of a rectangular prism whose length (l) = 8 units, width (w) = 5 units, and height (h) = 7 units?
Solution:
The surface area of the rectangular prism = 2( lw + wh + lh)
= 2( 8 × 5 + 5 × 7 + 8 × 7)
= 2(40 +35 + 56)
= 2 × 131
= 262 square units.

Example2:
Find the volume of a rectangular prism whose length is 7 units and width is 9 units and height is 8 units.
Solution:
The volume of rectangular prism = l × w × h
= 7 × 9 × 8
= 504 cubic units.
Similarly, you can try the calculator to find the surface area and volume for
 Length = 9 units, width = 6 units and height = 12 units
 Length = 5 units, width = 3 units and height = 8 units
