18 ft= 54 yds.
a square has four equal sides, so 54 times 54 equals 2,916
Your answer is 2,916 square yards
That's a convoluted way to ask a simple question. 14.
M= A- 3y
And it’s that bc I did I on the test
Surface area=2A + BH
where A is the area of the base, B the perimeter of the base and H the height.
S.A=2*4.5*6 +2(4.5+6)*12
S.A=54+252
S.A= 306 sq. inches
1 thousand a month would be my guess
