Dimensions of a Suitcase
To determine how much tarpaulin is needed to cover one suitcase, we first calculate the surface area of a single suitcase with dimensions 80cm x 48cm x 24cm.
Surface Area Calculation
The formula for the surface area (SA) of a rectangular box is:
\[ SA = 2(lb + bh + hl) \]
Where:
- \( l \) = length = 80 cm
- \( b \) = breadth = 48 cm
- \( h \) = height = 24 cm
Calculating each component:
- \( lb = 80 \times 48 = 3840 \, \text{cm}^2 \)
- \( bh = 48 \times 24 = 1152 \, \text{cm}^2 \)
- \( hl = 24 \times 80 = 1920 \, \text{cm}^2 \)
Now, substituting into the surface area formula:
\[ SA = 2(3840 + 1152 + 1920) = 2(6912) = 13824 \, \text{cm}^2 \]
Total Surface Area for 100 Suitcases
To find the total surface area for 100 suitcases:
\[ Total \, SA = 100 \times 13824 \, \text{cm}^2 = 1382400 \, \text{cm}^2 \]
Conversion to Square Metres
Now, convert the total surface area from cm² to m² (1 m² = 10,000 cm²):
\[ Total \, SA \, in \, m² = \frac{1382400}{10000} = 138.24 \, m² \]
Calculating the Length of Tarpaulin Required
Given the width of the tarpaulin is 96 cm (0.96 m), we can find the length required using the formula:
\[ Length = \frac{Total \, SA}{Width} \]
Calculating the length:
\[ Length = \frac{138.24 \, m²}{0.96 \, m} \approx 144 \, m \]
Conclusion
To cover 100 suitcases, approximately 144 metres of tarpaulin cloth is required.
