Mr. mcneely has a wooden box in the shape of a right rectangular prism. the box measures 2
feet by 3 feet by 2.8 feet. what is the surface area of the box?

40ft^2

Step-by-step explanation:

multiply :

2(2*3)

2(2*2.8)        

2(3*2.8)

Each value in the parenthesis are the areas of 3 different sides. You then multiply by two because there is another side opposite to the side that is the same.

then add all of those up

you get 40

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it

0.32
