- Surface area
- 65.423 292
Show the working
- Base length = 5
- Base width = 3
- Height = 6
- Volume = 5 * 3 * 6 / 3 = 30
- Surface area = 5*3 + 5*hypot(3/2, 6) + 3*hypot(5/2, 6) = 65.4233
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.
