Answer:

V=250\ cm^{3}

Step-by-step explanation:

step 1

Find the length of the base L

we know that

The surface area of a rectangular prism is equal to

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

substitute

SA=2(LW)+2(L+W)H

we have

W=5\ cm

H=10\ cm

SA=250\ cm^{2}

substitute in the formula and solve for L

250=2(5L)+2(L+5)10

250=10L+20L+100

30L=250-100

L=5\ cm

step 2

Find the volume of the rectangular prism

The volume is equal to

V=(LW)H

we have

W=5\ cm

L=5\ cm

H=10\ cm

substitute

V=(5*5)*10=250\ cm^{3}

The equation of a line is -6x-2y=-18<br> What is the x-intercept of the line?
Fed [463]

 -6x - 2y = -18

-6x - 2(0) = -18

   -6x - 0 = -18

        -6x = -18

         -6      -6

           x = 3

hope this helps :)

The sides of two cubes are in the ratio 2:1. What is the ratio of their volumes ?
olasank [31]

Please mark as brainliest

Answer:

we know that, Volume of cube=a³

Let volume of 1st cube be 2x with side a and other be x with side A (according to given ratio)

Step-by-step explanation:

ATQ: 2x=a³ and, x=A³

a=³√2x and, A=x

we know that, surface area of cube is 6a²

Thus, surface area of 1st cube = 6(³√2x)²

= 6³√4x²

Surface area of 2nd cube=6(x)²=6x²

Ratio of S.A=(6³√4x²)÷(6x²)

Ratio of S.A=³√4:1

Have a great day, be safe and healthy
