<u>Answer:</u>
<h2>
SA = 254 cm²</h2>
<u>Steps:</u>
SA = 2(L×W) + 2(H×L) + 2(H×W)
given:
L = 9 cm
W = 4 cm
H = 7 cm
SA = 2(9×4) + 2(7×9) + 2(7×4)
SA = 2×36 + 2×63 + 2×28
SA = 72 + 126 + 56
SA = 254 cm²
You can do this:
6 * ? = 48, ? = 8, so you multiply the five by 8 too, and you find that x = 40. Another method you can use would just to be to add 5 to the top and 6 to the bottom until the denominators equal each other.
16/20. We reduce that and get 4/5.
After this it's much simpler to chage it.
100 dividied by 5 is 20. (20,40,60,80,100)
So the 4th number (4/100)
is 80. 80%.
20% she didn't and 80% she did :) (100-80)
