Compute the surface area of the cuboid. The edges are decimals — be careful with the arithmetic.
S = 2 · (a·b + b·c + a·c)
Surface area S: cm²
What does this generator do?
The generator picks edges a, b, c from values like 2, 2.5, 3, 3.5 … 8 (at least one decimal). Compute the surface area in cm².
How to solve it
Use the formula S = 2·(a·b + b·c + a·c). Work out the three pairwise products first, sum them, then multiply by 2. With decimals it helps to multiply two decimals first and add whole numbers afterwards.
