The answer will depend on the shape (and size) of the box: some have a rectangular cross-section, others circular.
To calculate the surface area of a rectangular box, use the formula: Surface Area = 2(lw + lh + wh), where l is the length, w is the width, and h is the height of the box. Simply plug in the values for length, width, and height to find the total surface area. Make sure to calculate each area of the three pairs of opposite faces and then sum them up, multiplying by 2 to account for both sides.

To calculate the surface area of a box (rectangular prism), use the formula: Surface Area = 2(lw + lh + wh), where l is the length, w is the width, and h is the height. For a box measuring 20 cm by 10 cm by 15 cm, the surface area is: 2(2010 + 2015 + 10*15) = 2(200 + 300 + 150) = 2(650) = 1300 cm². Thus, the surface area of the box is 1300 cm².
To find the box with the least surface area for a given volume, you can start by using the formula for the surface area of a rectangular box: ( SA = 2(lw + lh + wh) ), where ( l ), ( w ), and ( h ) are the box's length, width, and height. Given a specific volume ( V = lwh ), you can express one dimension in terms of the others and then use calculus to minimize the surface area function. Typically, the optimal box shape with the least surface area for a fixed volume is a cube, as all sides are equal. You can confirm this by applying the method of Lagrange multipliers or analyzing the critical points of the surface area equation.
Multiply length x width.
Measure the height and multiply it by the width.
The answer will depend on the shape (and size) of the box: some have a rectangular cross-section, others circular.
you multiply the length times width times height.
