Volume of a prism = Base area x height

The base is a trapezium

\begin{gathered} \text{Base area = }\frac{1}{2}(a+b)h \\ =\frac{1}{2}(5+2)6 \\ =\frac{1}{2}(7)6 \\ =21ft^2 \end{gathered}\begin{gathered} \text{Volume = 21 ft}^2\text{ x 10}\frac{1}{2}\text{ ft} \\ =21\text{ x }\frac{21}{2} \\ =220.5ft^3 \end{gathered}

Two triangles can be formed with the given information. Use the Law of Sines to solve the triangles. C = 71°, a = 27, c = 26
guajiro [1.7K]

We have

SinC/ c  = Sin A / a

Sin 71/ 26 = Sin A / 27

Sin A  = 27 Sin 71 /  26  = about .982

So°

Sin-1(.982)  = A  = 79. 08°

Then angle B = 180 - 71 - 79.08 = 29.92°

And b is given by

b/sin29.92  = 26/sin 71

b = 26sin29.92/sin71 =  about 13.72

But A could also be an obtuse angle = 180 - 79.08 =  100.92°

So we have

B = 180 - 71 - 100.92 = 8.08°

And we have

b / sin 8.08  = 26/sin71

b = 26sin8.08/sin 71 = 3.865
