The edges of a cube are 5 cm each and the diaganol of a face is approximately 7 cm what is the approximate area of the cross section passing through the diagonal of opposite faces of this cube

The approximate area is 35 square centimeters

Step-by-step explanation:

we know that

The cross section passing through the diagonal of opposite faces of the cube is a rectangle

so

the approximate area is equal to

where

b is the diagonal of a face

h is the length side of the cube

we have

substitute

20

step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
