Mathematics

$Volume = 24\ ft^3$

Step-by-step explanation:

Given [Missing from the question]

$Length = 170cm\\ Width = 100cm\\ Height = 40cm$

Required

Determine the volume

This is calculated as:

Volume = Length * Width * Height

Volume = 170cm * 100cm * 40cm

Volume = 680000cm^3

Convert to cubic foot [Divide by 28317 ]

$Volume = \frac{680000\ ft/^3}{28317}$

$Volume = 24.0138432744\ ft^3$

$Volume = 24\ ft^3$ --- approximated
