Answer:-16
Step-by-step explanation:
A box (cube) has all equal edges or sides (s), thus the volume (v) of the cube is:

So since each side or edge around is 3 in, then the length around the square bottom of the box = 4×3 = 12 in
Answer:
520 feets
Step-by-step explanation:
The height of the building, h can be obtuined using trigonometry ;
From the attached diagram, opposite side = 300 feets ; height, h = adjacent side
Hence,
Tan θ = opposite / Adjacent
Tan 30° = 300 / height
0.5773502 = 300 / height
Height = 300 / 0.5773502
Height = 519.615
Height = 520 feets
