Okay, the last person who edited this, totally screwed up. The formula to find the surface area of a square prism is 2B+Ph, multiply the length of the width of the base to get the area, then multiply that by two. After you have multiplied the base twice, et the perimeter of the base and multiply it by the height of the square prism.
If a rectangular prism has length L, width W and height H units, then its total surface area is 2*(LW + WH + HL) square units.
If the cubic prism has length L, breadth B and height H, then its surface area is 2*(LB + BH + HL) square units.
Volume of rectangular prism: 5*5*20 = 500 cubic cm
-- Measure the length, width, and height of the prism. -- Multiply the three numbers. The result is the volume of the prism.
you find a tape measure and find how wide and fat it is then you cut it into tinny little pieces and measure them and you will get the dimension of a prism

This square prism is a cube with six sides, each having an area of one square foot. Thus, the total surface area is six square feet.
the defnition of find the surface area of triangular prism and cylinder
If a rectangular prism has length L, width W and height H units, then its total surface area is 2*(LW + WH + HL) square units.
If the cubic prism has length L, breadth B and height H, then its surface area is 2*(LB + BH + HL) square units.
To find the surface area of an prism you must do the following: EXAMPLE: S.A.( SURFACE AREA) and L.A.(LATERAL AREA) S.A.=L.A. +2B S.A.=113 +2 (28) S.A.= 113 + 56 S.A.=169 IN.2( THE 2 MEANS SQUARE ROOT)
If the prism has length L, breadth B and height H, then total surface area = 2*(LB + BH + HL) square units.
Measure it.
You measure it.
find the area of triangles(reflecting surfaces) and also the area of rectangle or square(base)and find the sum of both.
The answer depends on the shape and dimensions of the prism. If the cross section is an equilateral triangle with sides of rational length then you will require a square root to find its area. You could, of course, have a 3-4-5 triangle, in which case no square root is required if the length is rational.
