Answer:
2160 BTU
Step-by-step explanation:
Ben looks at his plan and realizes that his building can be viewed as a triangular prism sitting on a cube.
Calculating the volume of a cube is easy… Length x Width x Height (LWH)… so 12 x 10 x 8 = 120 x 8 = 960 cubic feet for the cube part.
For the prism, it’s almost the same… but divided by 2 : (LWH)/2, so… (12 x 10 x 2) / 2 = (120 x 2) / 2 = 240 / 2 = 120 cubic feet for the prism part.
Total for the building : 960 + 120 = 1080 cubic feet
Since 2 BTU per cubic foot, the power of the unit needs to be at least 1080 x 2 = 2160 BTU.

Answer:
A. 23.6
Step-by-step explanation:
Let the dotted line be y
<u>Then</u>
- y/x = sin(50°) ⇒ x = y/sin (50°)
and
- 29/y = tan (58°) ⇒ y = 29/tan (58°)
<u>So </u>
- x = 29/tan (58°)/sin (50°) ≈ 23.6
<u>Correct answer is</u> A. 23.6
5 can go into 20 4 times. If 5 was already there then it is 400 times the original number or 5.
OR
5/100 = 20/x Rearrange x5 = 20x100 2000/5 = x x=400
