Answer:
435 in.²
Step-by-step explanation:
Surface area of the square pyramid = area of the square base + ½(Perimeter of base)(slant height)
Area of base = s²
s = 15 in
Area = 15² = 225 in²
Perimeter of the base = 4(15) = 60 in
Slant height = 7 in
Surface Area = 225 + ½(60)(7)
= 435 in.²
The answer is seven in the last question you didnt say that the 2 was also a exponent. :) - beanz
4 pupils can eat 12 because if you times 6 by 2 you get 12, so if you do the same to the other side then you'll get the answer 4 (2X2=4)
The equivalent to 27% is 0.27
