Question

What is the surface area of the right rectangular prism?

Answer 1

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:

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

Answer 2

Answer:

Surface Area = 31m^3

Volume = 6m^3

Step-by-step explanation:

We are given a diagram of a right rectangular prism and we are to find its surface area and its volume.

We know the formula of surface area of the right rectangular prism is given by: $Surface Area =2(wl+hl+hw)$

Substituting the given values to get the S.Area:

Surface Area = $2(3*4+0.5*4+0.5*3)=2(15.5)$ = 31m^3

While the formula for the volume of the right rectangular prism is given by: $V=whl$

Substituting the given values to get the volume:

Volume = $3*0.5*4$ = 6m^3
