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.
Answer:
B.
Step-by-step explanation:
if you want to check it would be
160 x 2.5 = 400
OR
400 / 2.5 = 160
i hope this helps!
Answer:
Do 180-110=70 Then have it where 70/2=35. 35+4=39, 35-4=31, so the three angles are 39, 110, and 31.
