Monica found the volume of the prism below using the expression . What errors did Monica make? Check all that apply.

She should have counted only 2 unit cubes instead of 4.

She should have counted 8 one-third cubes instead of only 4.

She should have found the total value of the one-third cubes by multiplying by instead of by .

Each fractional cube is worth instead of the that she used.

She cannot stack more than one layer of fractional cubes in a prism.

answer: (-8,4) are the coordinates of a

step-by-step explanation:

let the side of square abcd is x .

thus the area of square abcd is .

now, by the diagram area of triangle ead= 1/2 × ea × ad = 1/2 × ea × x

( because ad is the side of square)

and, according to the question,

the areas of square abcd and right ead are equal.

⇒

⇒ea=2x

thus, ea: ab=2: 1

therefore, point a divides line segment eb into the ratio 2: 1.

⇒ by sectional formula coordinates of a are,

=

=

=(-8, 4)

thus the coordinates of a are (-8,4)
