Hm let's see the answer should be by the definition of isosceles triangle
It's not a proper square root, but you're looking for a number between 25 and 26 (<span>25.6515106768)</span>
Heres an equation: 126/3 = 42
193.58 + d > = 200 : d > = 6.42...answer is A
Two figure in front
h=16+17 = 33 m
l=18 m
width = 13 m
Volume = lwh = 18*13*33 =7722 m^2
Two figures at the back
h=16 m
l=18+18 =36 m
width = 15 m
Volume = lwh =36*15*16 =8640 m^2
Total volume = 7722+8640 = 16362 m^2
