The riches are ordering topsoil for their new lawn. the topsoil will be spread evenly over the yard before the grass is planted. the yard is 81 feet wide and 111 feet long. the topsoil will be spread 2 inches deep. how many cubic yards of topsoil are needed?

$119.20

step-by-step explanation:

$372.50 - 60% off is $149. $149-20% off is $119.20

you bought 31 v bucks

step-by-step explanation:

25+6=31

the answer is: 5,953.2 mm²

you have the  8-sided octahedron as a composite figure that has 2 square pyramids. so, you should   apply the formula for the calculated area of a square pyramid as so:   a=s²+2sl

  a is the area of the square pyramid.

  s will be the base of the square pyramid (s = 33 mm).

  l is the slant height of the square pyramid (l = 28.6 mm).

then, when you substitute these values into the formula you get:

  a=s²+2sl

  a=(33 mm)²+2(33 mm)(28.6 mm)

  a=1089 mm²+1887.6 mm²

  a=2,976.6 mm²

thus, the area of the  surface area of the octahedron is:

sa = 2a

sa = 2(2,976.6 mm²)

sa = 5,953.2 mm²

thus the answer will be: 5,953.2 mm²

          √25                                         √33               √36      

i made this little number line up there for a visual example. : d

to find √33, you take the nearest root vales you know right off the bat. √25 and √36 which is 5 and 6, correct? and on the number line, you can see that √33 falls closer to √36, 6. so we know that √33 is going to be 5 point. something, right? but because 33 is so close to six, it is going to be a higher number for 5 point. something. so it is approximately 5.7
