We're given two sides and the included angle and asked to find the third side. That's the Law of Cosines.

$c^2 = a^2 + b^2 - 2 a b \cos C$

$c = \sqrt{15^2 + 20^2 - 2 (15)(20) \cos 50^\circ} \approx 15.5 \textrm{ feet}$

If the framed picture is shaped like a square and has a 12 square foot surface area, then the answer is yes, it will fit flush against the edge of the crate.

Given Part A:

the volume of the cube = 64 cubic feet

therefore, ∛64 = 4 feet

hence one edge measures 4 feet.

Now for Part B:

the area of the square is 12 square feet.

hence, √12 = 3.36 feet.

we can observe that 3.46<4

which indicates that the area covered by the painting is less than that of the one side of the crate, which makes it easy for the painting to fit in the crate.

Hence the painting will fit a side of crate.
