Question

The bed of a pickup truck measures 4 feet by 8 feet to the nearest inch, what is the length of the longest thin metal bar that will lie flat in the bed

Answer 1

The bed of the truck is a rectangle, 4-ft wide and 8-ft long.

The diagonal of the rectangle is

√ (4² + 8²)

= √ (16 + 64)

= √ (80)

= 8.9442... feet

8.9442... feet = 8 feett 11.33 inches

Rounded to the nearest inch: 8 ft 11 in .
