Answer:
<h3>The volume of the prism is cubic
centimeters.</h3><h3>
Step-by-step explanation:</h3><h3>Given that a rectangular prism has the following dimensions:</h3><h3>
</h3><h3>We know that a rectangular prism of length 'l', width 'w' and height 'h' is given by</h3><h3>
</h3><h3>Therefore, the volume of the given prism will be</h3><h3>
</h3><h3>Thus, the volume of the prism is
cubic centimetres.</h3>
Given:
Area(A)= 63m^2
Length (L)= 2W+5
Width (W)=?
A=LxW
63=(2W+5)(W)
63=2W^2 + 5W
0=2W^2+5W-63
0=(2W-9)(W+7)
2W-9=0 then W=4.5 and W+7=0 then W=-7
Can only use 4.5 since it is positive and distance is positive.
W= 4.5 m
L=2W+5=2 (4.5)+5=9+5=14m
Sin O = 1 / csc O = 2/9
cos O = sqrt (1 - (2/9)^2) = sqrt 77/81 = sqrt77 / 9
