a square pyramid has a height of 9 units and a volume of 147 units. if a square prism has the same base area and volume as the
square pyramid, what is its height?
1 unit
3 units
6units
9units

Option B.

Step-by-step explanation:

A square pyramid has a height = 9 units and volume = 147 unit³

Then By the formula,

Volume of pyramid =

                          147 =

                          147 = 3(Area of the base)

Area of the base = unit²

Now we have to find the height of a prism having same area of base and volume as the square pyramid.

Volume of a prism = Area of the base × height

We plug in the values of volume and area of the base

147 = 49×height

Height =

           = 3 units

Option B. is the answer.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
