Volume is 216 sorry if you get it wrong
7 because all the room contain 1//2 and Brandon has 7/1/2 i t pretty easy <span />
Answer:
137.5 in^2
Step-by-step explanation:
So, this is basically a rectangle and two right-sides triangles.
First the rectangle: Formula is A=wl
Replace the Values: A = 14*7 98 in^2
Then we solve for the two right-sides triangles.
A= 1
/2a
h=
1
/4
b
^2
sin
(2
θ
)
Top trinangle= A = 25.5 in^2 (height 7 in base 7 in)
Bottom Trinagle A = 14 in^2 (height 7 in base 4 in)
Add results:
98+25.5+14 = 137.5 in^2
Subtract the two numbers and you will get the answer
