Help me whit this pls

320

Step-by-step explanation:

The formula for the volume of a pyramid is V= (b x h)/3

v is the volume

b is the base you get it by multiplying the bases length and width in this case it would be 80 in( since 8 x 10 is 80)

h is the height in this case it would be 12 in

V= (b x h)/3

V= (80 x 12)/3

V= (960)/3

V= 320 in

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!
