1O piramida triunghiulara regulata are latura bazei a si muchia laterala 2a. Sa se afle volumul si aria laterala a piramidei.

2...O piramida patrulatera regulata are muchia laterala de 10cm si inaltimea de 8.se cer:

a)Latura bazei

b)Volumul piramidei

Repede dau funda :)

1. a^3/6 (15)^{1/2}

2.

a. a = 12 cm

b. V = 384 cm^3

Step-by-step explanation:

1. The volume of rectangular pyramid is given by:

b: base area = a^2

h: height

c: side edge = 2a

"h" can be calculated by using the Pitagora's theorem:

The, the volume is:

2.

a. The side base is calculated by using the Pitagora's theorem again:

b. The volume is given by:

x/3-10=8

x/3=18

x=48

idk

step-by-step explanation:
