Answer:

The answer to your question is Volume = 12735.06 cm³

Step-by-step explanation:

Data

a = 11.26 cm

s = 13 cm

h = 29 cm

Formula

V = BH

Process

1.- Calculate the area of the base

Area = B = Pa/2

P = Perimeter

P = 6(13)

P = 78 cm

Area = (78)(11.26)/2

        = 878.28/2

       = 439.14 cm²

2.- Calculate the volume

Volume = BH

             = (439.14)(29)

             = 12735.06 cm³
