The solid was created by connecting two congruent square pyramids to a rectangular prism.
AnnyKZ [126]

Answer:

  1920 square inches

Step-by-step explanation:

For a rectangular prism, the lateral area can be found by ...

  LA = Pl

where P is the perimeter, and l is the length.

For a square pyramid, the lateral area can be found by ...

  LA = (1/2)Ph

where P is the perimeter of the base, and h is the slant height of the triangular faces.

For a figure with a square cross section of perimeter P "capped" by square pyramids on either end, the total surface area is the sum of the lateral areas of the three components:

  SA = (Pl) + (1/2)Ph + (1/2)Ph

  SA = P(l+h) = (4×15 in)(14 +18 in) = (60)(32) in²

  SA = 1920 in²

The surface area of the solid seems to be 1920 square inches.

<em>Caveat</em>

If the figure is something other than what we have tried to describe, your mileage may vary. A diagram would be helpful.

makkiz [27]

Answer:

100,000,000,000

Step-by-step explanation:

10^6 = 1,000,000. So one million computer programmers.

They're all making 10^5. So 100,000.

1,000,000 * 100,000, since every single one is making 100k.

Therefore, $100,000,000,000 is your answer.

Remember not to include the dollar sign!

A can is in the shape of a right circular cylinder. The circumference of the base of the can is 12 inches, and the height of the
MariettaO [177]

Answer:

the length of the stripe is 20.82inches

Step-by-step explanation:

given

height of can = 5in

circumference = 12in

π = 3.142

the circumference of the base = 2πr = 12

                radius of base = 1.91in

if the stripe wind once round the can (circumference length), it will start from the radius base to the radius top.

the total length of the stripe = 2radius + circumference of can + height

= 2(1.91) + 12 + 5 = 20.82inches
