Answer:
24 Meters Cubed
Step-by-step explanation:
If 3m is the length of the base edge, and 8 is the height, then the answer would be 24 Meters cubed. The formula for a square trapezoid is V=a squared times height/three.
S^2
SxS
S^(S-1)xS
Any of those should work
Y/6 = 8/11
cross multiply
(11)(y) = (8)(6)
11y = 48
y = 48/11
y = 4.36 rounds to 4.4 <==
88 + 89 + 79 + 77 = 333. 420-333= 87. The minimum score he can get is 87
