How is the process of finding the surface area of a rectangular prism the same as finding the surface area of a triangular prism
harina [27]

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

8(7 + 23) = 8(7) + 8(?)
34kurt
Answer: 23

When using multiplication with brackets, you multiply the number by all the numbers within the bracket before adding them together.

Therefore when it is 8(7 + 23) it basically means: 8(7) + 8(23)
