Find the total surface area of these solids

4 0
<h2>Step-by-step explanation:</h2><h3>We firstly find the surface area of only one face of the cube:</h3><h3>Sa=a²</h3><h3>Sa=1.2²cm</h3><h3>Sa=1.44cm²</h3>

<h2>Since the cube has 6 faces we multiply the surface area of one face(144cm²) with 6</h2>

Area(cube)=1.44cm²*6

=8.64cm²

<h2>Same thing with the prism but we have to find the area of one of his triangle face and rectangle face</h2>

S(triangle)=5mm*4mm*1/2

=10mm²

S(rectangle)=7mm*5mm=35mm²

<h2>The prism has 2 triangle faces and three rectangle faces so we multiply the area by those numbers and then we add those together to get the final area</h2>

S=10mm²*2+35mm²*3

S=20+105

S=125mm²

Divide using a common factor of 6 to find an equivalent fraction for
Savatey [412]

5: six twelfths is one half

6: eight tenths is four fifths

7: four eighths is one half

8: ten tenths is two halves

9: two sixths is one third

10: one quarter, because you divide the top and bottom number by 3

method:

take the first one - four eighths, which is 4/8

the question gives you what to divide them by, 4, so u divide both the top number and bottom number to get 1/2, which is one half :)

A right circular cylinder has a volume of 500 cu in. If the base has a radius of 4 in., what's the altitude of the cylinder? Rou
trasher [3.6K]
Hello!

The area of a cylinder formula- Area = Pi * radius squared * height 

<span>In this case we are looking for height (altitude) </span>

<span>plug in our known values </span>

<span>500 = area </span>
<span>4 = radius </span>
<span>Pi ~ 3.141592654 </span>

<span>to find height... </span>

<span>500 = 3.141592654 * (4)^2 * height </span>

<span>500 = 3.14 * 16 * height </span>

<span>500 = 50.26 * height </span>

<span>divide both sides by 50.26.. </span>

<span>9.947 = height 
</span>

<span>9.95 is the Correct Answer ( letter C)
</span>
Hope this Helps! Have A Wonderful Day! :)

The area of the shaded face is 96 square centimeters.
Masja [62]

Answer:

I think the answer will be 32,768 cubic units..

Step-by-step explanation:

The volume formula is length times width times height and you say that the area of the shaded face is 96 square cm is better we divide

96/3 =32

So, we took the colume formula like this:

V= L x W x  H

  = 32 x 32 x 32

  =  1,024    x  32

  =   32,768 cubic units
