Find the volume , including units of a square pyramid with base length 5 cm and height 6cm

50 cm^2

Step-by-step explanation:

The volume of a square pyramid can be found using:

v= 1/3 bh

Where b is the area of the base, and h is the height

First, we have to find the area of the base

a=l*w

In a square, all sides are equal, so we know the length and the width are both 5

a=5*5

a=25

Now, we can substitute 25 in for b, and 6 in for h

v=1/3bh

v=1/3(25*6)

v=1/3(150)

v=50

Volume uses units cubed, and in this case our units are centimeters

The volume is 50 cm^3

R=rita's age
m=mother's age
g=grandmother's age

mother is 4 times as old as rita
m=4r

grandmother is 2 times as old as mother
g=2m

sum is 104

r+m+g=104
subsitute 4r for m and 2m for g
r+4r+2m=104
subsitute 4r for m
r+4r+2(4r)=104
r+4r+8r=104
13r=104
divide both sides by 13
r=8
4r=m=32
8r=2m=g=64

rita is 8
mother is 32
grandmother is 64
