                                 = 0.5 ft, 0.25 ft

New bed dimension of room = \frac{1}{12} \times 14 ft, \frac{1}{12} \times 16 ft

                                                 = 1.16 ft, 1.33 ft

A triangle has a base of 17 inches and a area of 127.5 square inches. What is the height of the triangle?
zmey [24]
We know that area=0.5*base*height.

Thus, the equation would look like:
127.5=0.5*base*height

That means, 255 = base*height.
We know base is 17
Then, we divide 255 by 17. That gets us the height.
The height equals 15.

Step-by-step explanation:

The volume of the smaller box is (1 ft)³ = 1 ft³. So 64 of them require a box with a volume of 64 ft³.

The most compact of such boxes is one that is cube-shaped itself. Such a box would have dimensions of ...

  ∛(64 ft³) = 4 ft

A box that is 4 ft × 4 ft × 4 ft would hold the 64 smaller boxes.
