Answer:

Solution given:

for triangle

base=3in

height=2in

and

length=7in

we have

Volume of triangular pyramid=area of triangle *length

  • =½(base*height)*length
  • =½(3*2)*7
  • 21in³

21in³ is a required volume.

Height of base

  • √2.5²-(3/2)²
  • √2.5²-1.5²
  • √6.25-2.25
  • √4
  • 2

Area of base

  • 1/2BH
  • 1/2(2)(3)
  • 3in²

Volume

  • Area of base×Height
  • 3(7)
  • 21in³
