How many cubic feet of dirt are there in a hole that is 3’ deep x 3’ wide x 3’ long?

Step-by-step explanation:

We are given that a hole

Length of hole=3 ft

Width of hole=3 ft

Depth of hole= 3ft

We have to find the volume of dirt are there in hole.

Volume of hole=Volume of dirt

Volume of dirt=

Substitute the values then we get

Volume of dirt=

Hence, the volume of dirt in a hole =

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
