Question

A spear of 5.4 ft is inserted in a wooden box as shown.

What is the approximate width of the base?

Answer 1

5

Explanation:

3x3= 9

4x4= 16

you get 25 and then square root it

Answer 2

The answer is "2 ft"

Explanation:

In the given question some information is missing, that is attachment of diagram, which can be described as follows:

Given value:

D= 5.4 ft

length = 3

base = 4

width= ?

Formula:

`D= √(\ length^2 + \ base^2 + \ width^2) \\\\`

`5.4 = √(3^2+4^2+ width^2)\\\\5.4 = √(9+16+width^2) \\\\5.4 = √(25 +width^2).......(i)\\\\`

Square the above equation.

`(5.4)^2 = (√(25+width^2))^2\\\\`

`29.16 = 25 +width^2\\\\29.16-25 = width^2\\\\width^2 = 4.16 \\\\width = 2.03 \ \ or \ \ 2`
