PLEASE HELP ME WITH THIS ITS MY LAST PROBLEM THANKS

The answer to your question is V = 82.5 in³

Step-by-step explanation:

Data

V = BH

a = 2.75 in

side = 4

height = 3 in

Process

1.- Calculate the area of the base (B)

B = Pa/2

P = number of sides x length of a side

  = 5 x 4

  = 20 in

B = (20)(2.75)/2

B = 55/2

B = 27.5 in

2.- Calculate the volume of the prism

V = (27.5)(3)

V = 82.5 in³

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
