A shoe.
4 unit i think
Honestly you could use any unit of measure! I would use inches. Thanks Cheezpuffz
1 liter
It wouldn't be called girth; instead, it would be called dimensions of a box. To find the dimensions, measure length x width. To know the area of the sides of a box, it would be length x width x depth (how tall it is).
The weight of the box would be measured in grams.
A scale
Mass= Kg (Kilograms) Weight= N (Newtons) or if your measuring volume, then it would be: cm3 (Centimeters Cubed)
a ruler is the measuring tool. The type of unit you will use is cm and mm
1.3 m square cannot be a measure of how far the box moves because metre square is a measurement unit for area - not distance. The question is therefore nonsense and cannot be answered.
It would be one box.
The same way you measure the volume of any other box, or any other rectangular prism: -- Measure the length. -- Measure the width. -- Measure teh height. -- Multiply (length) x (width) x (height). The product is the volume of the box.
I suggest you use liters.
The tool used would be a scale or balance. You might have to use a box to keep it from rolling off the scale surface. Measure the mass of the box, then the mass of the combination then subtract the box's mass. Common unit is pounds in the United States (that's how they are designated), and I'd guess kilograms in other countries.
