Question

A rectangular aquarium with a base of 3 in. By 4 in. And a height of 12in. What is the longest piece of wood you can place in diagonally in the tank

Answer 1

Explanation:

:P nice points ty :)

find the length of the long diagonal across the tank.

first find the 2D diagonal , then use that dist. to find the long 3D diagonal

`C^(2)` =
`3^(2)`+
`4^(2)`

C = 5 (2D)

now find the 3D

`C^(2)` =
`5^(2)`+
`12^(2)`

C = 13 inches

( they made it easy ) :)
