The volume of a rectangular prism is 270 cubic centimeters. The height of the prism is 5 centimeters. What should the length and width of the prism be? Explain your solution strategy.

Answers

V=volume h=height l=length w=width
V=h•w•l
w•l=v/5
w•l=270/5
w•l=54
Since this is all we know, we can't tell what the width or length really is but we can give examples: 6 and 9 (or 9 and 6), 4 and 13.5 (or the other way round), 18 and 3 (or 3 and 18), 2 and 27 (or 27 and 2).

5cm (H), 9cm (L), 6cm (W).

5 times 9 is 45 times by 6 (240 plus 30=) 270 CC

Or You could just have numbers for L and W which equal 54 because 5 times by 54 is 270.

If a cone has a surface area of 822.78cm^2 and a diameter of 18cm, find the slant height of the cone

Answers

Answer:

$20.11\ cm$

Step-by-step explanation:

we know that

The surface area of the cone is equal to

$SA=\pi r^(2)+\pi rl$

where

r is the radius

l is the slant height

In this problem we have

$SA=822.78\ cm^(2)$

$r=18/2=9\ cm$ -----> the radius is half the diameter

substitute and solve for l

$822.78=\pi (9)^(2)+\pi (9)l$

$822.78=81\pi +9\pi l$

$l=(822.78-81\pi)/9\pi$

$l=(822.78-81(3.14))/9(3.14)=20.11\ cm$
