identify and explain the error *

show correct work and solution *

what strategy did you use for solving this problem *

1: she used the wrong formula

2: 36cubic feet

3: the strategy: knowing that to find the volume of a rectagle is l*w*h and subtituting in the correct numbers

Step-by-step explanation:

1: to find the volume of a rectangle is height*width*length

2: you multiply 6*5*1.2 and you should get 36 and sice you are finding volume it is cubic and the measurment

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
