The cube has 6 this same faces.
Therefore the surface area is equal 6 · 7cm² = 42cm²
Answer:
Step-by-step explanation:
Mass m=25 g
Volume V=1.29 cm³
density D=M/V
=25/1.29
≈19.38
≈19 g/cm³
Set it up as a ratio:
mans shadow over mans height (4/6 ) equals flag pole shadow over flag pole height (15/x)
set them to equal each other:
4/6 = 15/x
cross multiply: 4*x =4x, 15*6 = 90
so you have 4x = 90
now divide both sides by 5 to solve for x, which is the height of the flag pole:
x = 90 / 4 = 22.5 feet tall
