Question

10. A cardboard box measures 40 cm by 40 cm by 30 cm. Calculate the length of the space diagonal, to the nearest centimetre.

Answer 1

Answer: 64 cm

Work Shown

`\text{d} = \sqrt{\text{x}^2+\text{y}^2+\text{z}^2}\\\\\text{d} = √(40^2+40^2+30^2)\\\\\text{d} = √(4100)\\\\\text{d} \approx 64.031\\\\\text{d} \approx 64\\\\`
