Question

How is the process of finding the surface area of a rectangular prism the same as finding the surface area of a triangular prism? How is it different?

ANSWER:
For both prisms, you can draw a net to help you find the areas of the faces. Add the areas together to find the surface area. A rectangular prism has only rectangular faces, and you use the formula bh to find area. A triangular prism has triangular and rectangular faces, and you use the area formula bh for rectangular faces and the area formula 1/2bh for triangular faces.

    Answer:

    see the explanation

    Step-by-step explanation:

    we know that

    The surface area of a prism is given by the formula

    SA=2B+PH

    where

    B is the area of the base

    P is the perimeter of the base

    H is the height of the prism

    For both prism the formula is the same

    How is it different?

    Rectangular prism

    The area of the base is given by the formula

    A=LW —–> is the area of rectangle

    where

    L is the length and W is the width of rectangle

    The perimeter of the base is given by

    P=2(L+W) —> is the perimeter of rectangle

    The height H is the same in both cases

    Triangular prism

    The area of the base is given by the formula

    A=\frac{1}{2} (b)(h) —–> is the area of the triangular base

    where

    b is the base of triangle and h is the height of triangle

    The perimeter of the base is given by

    P=(a+b+c) —> is the perimeter of triangle

    where

    a, b and c are the length sides of triangle

    The height H is the same in both cases

    Answer:

    for PLATO users

    Step-by-step explanation:

    The area of the face of the rectangular prism as determined above is 7×2 − 7x + 3.

    Area = length x depth

    Length = area ÷ depth

    Therefore, the length is (7×2 − 7x +3) ÷ (x + 4)

    Using synthetic division, the coefficients of the polynomial are 7, −7, 3, and k = −4.

    − 4

    7

    − 7

    3

    − 28

    140

    7

    − 35

    143

    Therefore, the length of the rectangular prism is given by . 7x-35+143/x+4
