A rectangular prism has a length of 20 in., a width of 2 in., and a height of 3<img src="https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%
vodomira [7]

Calculate the volume of both the prism and the cubes:

Prism:

Volume = 20 x 2 x 3.25 = 130 cubic inches.

Volume of cube:

Volume = S^3 = 1/4^3 = 1/64 ( 0.015625)

Divide the area of the prism by the area of the cube:

130 / 1/64 = 130 * 64 = 8,320

It would take 8,320 cubes to fill the prism.

Sue is upholstering a rectangular ottoman that measures 21 centimeters by 18 centimeters by 15 centimeters. What will be the tot
Anika [276]

Answer:

1926cm²

Step-by-step explanation:

Given

Dimension = 21cm by 18cn by 15cm

<em>The illustration in this question is to determine the surface area of the fabric and this is calculated using the surface area of a cuboid as follows:</em>

<em></em>

Surface\ Area =2(LB + LH + BH)

Where L, B and H are the dimensions.

So,

Surface\ Area = 2(21 * 18 + 21 * 15 + 18 * 15)

Surface\ Area = 2(378 + 315 + 270)

Surface\ Area = 2(963)

Surface\ Area = 2 * 963

Surface\ Area = 1926cm\²

<em>Hence, 1926 cm² of fabrics are needed to cover all surfaces.</em>

(X^3+1)dividend (x-1)
bazaltina [42]

x^3=x\cdot x^2 and x^2(x-1)=x^3-x^2. So we have a remainder of

(x^3+1)-(x^3-x^2)=x^2+1

x^2=x\cdot x and x(x-1)=x^2-x. Subtracting this from the previous remainder gives a new remainder

(x^2+1)-(x^2-x)=x+1

x=x\cdot1 and 1(x-1)=x-1. Subtracting this from the previous remainder gives a new one of

(x+1)-(x-1)=2

and we're done since 2 does not divide x. So we have

\dfrac{x^3+1}{x-1}=x^2+x+1+\dfrac2{x-1}
