Prism A 4x1x2=8
prism B 8x2x4=64

8/64 is the ratio, simplified would be 1/8

Prism A 6x2x3=36
prism B 12x4x6=288
36/288. simplified would be 1/8

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

problee cuz u onle give 5 point

Find the area of the base and multiply it by the height (C)

for PLATO users

Step-by-step explanation:

The area of the face of the rectangular prism as determined above is 7x2 − 7x + 3.

Area = length x depth

Length = area ÷ depth

Therefore, the length is (7x2 − 7x +3) ÷ (x + 4)

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

− 4

− 35

143

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