An office building has the shape of a right rectangular prism with a width 20 meters. length 40, height 60. draw the shape of one floor of the building. label the dimensions of your drawing.

The draw in the attached figure

Step-by-step explanation:

we know that

An office building has the shape of a right rectangular prism with a width 20 meters. length 40, height 60

so

The shape of one floor of the building is equal to the shape of the rectangular base of the prism

therefore

One floor of the building is a rectangle with

Length 40 m

Width 20 m

see the attached figure

The answer is part a: use

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
