It should be 376,656 ft^2 bc
1. square the bases (456 x 456 = 207936)
2. four triangles 4(1/2 x base x height) which would be 4(1/2 x 456 x 185) = 168720
then add up 168720 + 207936 = 376656
hope this helps :D
Answer:

Step-by-step explanation:
1) Expand

2) Simplify 6x - 36 - 5x + 35 to x - 1.

3) Cancle x on both sides.

4) Since −1 = 6 is false, there is no solution.
No Solution
Hence, this equation have no solution.
The answer to that problem is 9600cm. each side of surface area will be the same multiplied together
To put words into equations:
x+y+z =50
x=4y
4y=5z -> z= 4/5 y
Which means
4y+y+ 4/5 y= 50
29/5 y =50
29y=250
Y=29/250
Add 13 to both sides
13 = 2x + 15x
Simplify right side
13 = 17x
Divide through by 17
13/17 = x
