Can someone help me please
Brainiest answer to whoever is first

Step-by-step explanation:

Surface area of small box = 2(4×10) + 2(4×14) + 2(10×14)

= 2(40+56+140)

= 472 cm²

Surface area of large box = 2(4×20) + 2(4×14) + 2(20×14)

= 2(80+56+280)

= 832 cm²

832 - 472 = 360 cm²

i dont know what you want me to answer for this but im guessing 2: 11?

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)
