To solve this, we must know the formula for surface area of a rectangular prism. The formula solves for 3 of the faces, and then multiplies by 2, because in a rectangular prism, 2 opposite sides will always be equal.
The formula is 2(wl+hl+hw)
Now all we have to do is substitute in our values and solve.
2(wl+hl+hw)=
2(12*11+11*11+11*12)=
2(385)=
770=
Using the math above, we can see that the correct answer is A. 770 square cm.

Step-by-step explanation:
65% of 80= 52
82% of 50= 41
170% of 30= 51
Order: 82% of 50, 170% of 30, 65% of 80
Answer:
24 square feet
Step-by-step explanation:
To find the amount of square feet, find the area, using the formula A = lw
Plug in the length and width:
A = lw
A = (4)(6)
A = 24
So, the quilt is 24 square feet
The answer would be B, which is negative two.
