Answer:
1/6 of a yard
Step-by-step explanation:
Length of the board = 5/6 yard
He needs to cut the board into 5 equal sections.
Length of each section = length of the board ÷ number of sections
= 5/6 ÷ 5
= 5/6 × 1/5
= (5*1)/(6*5)
= 5/30
= 1/6
Length of each section = 1/6 of a yard
A balloon is a sphere and the volume of a sphere is V=4/3 π.R³
V= 4/3.π.(6³) = 4/3.π.216 = 288π unit³ or ≈ 905 unit³
According to the calculations made, 410 gumballs will be needed to fill the box.
Since you are trying to figure out how many gumballs you need to fill a 7.3 x 5.0 x 9.4 rectangular box for Halloween, and each gumball has a radius of 1/2 in, if the packing density for spheres is 5/8 of the volume will be filled with gumballs while the rest will be air how many gumballs will be needed, to determine this amount the following calculation must be performed:
- (Volume of box x 5/8) / volume of gumballs = Amount of gumballs
- Volume of a sphere = 4/3 x 3.14 x (radius x radius x radius)
- Volume of a gumball = 4/3 x 3.14 x (0.5 x 0.5 x 0.5) = 0.5235 inches
- ((7.3 x 5 x 9.4) x 5/8) / 0.523 = X
- (343.1 x 5/8) / 0.523 = X
- 214.4375 / 0.523 = X
- 410 = X
Therefore, 410 gumballs will be needed to fill the box.
