ANSWER FAST PLEASE!

Answer 1

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.

Answer 2

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
