What is the volume (in cubic centimeters) of a cube with 4cm sides?

1 answer:

8 0

I think it is 64 just multiply 4 times 4 times 4 because of the sides and to find volume you need to multiply the sides and the height so it should be 64.

What is the surface area of the right rectangular prism?

Mkey [24]

Answer:

1) OPTION D.

2) OPTION D.

Step-by-step explanation:

1) You can calculate the surface area of the rectangular prism with the following formula:

$SA=2(wh+lw+lh)$

Where w is the width, h is height and l is the length.

The figure show you that:

$l=4m\\w=3m\\h=0.5$

Then, the surface area is:

$SA=2[(3m*0.5m)+(4m*3m)+(4m*0.5m)]=31m^{2})$

2) You can calculate volume of the rectangular prism with the following formula:

$V=lwh$

Where w is the width, h is height and l is the length.

When you substitute values, you obtain the following result:

$V=4m*3m*0.5m=6m^{3}$
