A pyramid shaped building is 836 ft tall with a square base that is 156 ft on each side. What is the volume of the pyramid?

pishuonlain [190]

Answer:

6781632 ft ^ 3

Step-by-step explanation:

The first thing is to know the formula for the volume of a pyramid:

V = 1/3 * Ab * h

That is, it is one third of the product between the area of the base and the height.

The base area would be:

Ab = l ^ 2

the side equals 156 ft, replacing:

Ab = 156 ^ 2

Ab = 24336 ft ^ 2

now, replacing in the volume formula:

V = 1/3 * 24336 * 836

V = 6781632

Which means that the volume of the pyramid is 6781632 ft ^ 3

Calculate the total budget and then fill in the missing percentages (to the nearest tenth). Item $ % Contributions $175.76 Housi

Alik [6]

Answer:

Total Budget = 1,116

Contributions = 175.76/1,116 = 15.8%

Housing = 350.84/1,116 = 31.4%

Transportation = 50/1,116 = 4.5%

Clothing = 30/1,116 = 2.7%

Medical expenses = 35/1,116 = 3.1%

Food = 200/1,116 = 17.9%

Taxes = 106.40/1,116 = 9.5%

Miscellaneous = 168/1,116 = 15.1%

Step-by-step explanation:

Let's calculate the total budget and the percentages (to the nearest tenth).

Total Budget = 175.76 + 350.84 + 50 + 30 + 35 + 200 + 106.40 + 168

Total Budget = 1,116

Contributions = 175.76/1,116 = 15.8%

Housing = 350.84/1,116 = 31.4%

Transportation = 50/1,116 = 4.5%

Clothing = 30/1,116 = 2.7%

Medical expenses = 35/1,116 = 2.7%

Food = 200/1,116 = 17.9%

Taxes = 106.40/1,116 = 9.5%

Miscellaneous = 168/1,116 = 15.1%
