That usually depends on the flashlight. an average sized one is about 8Cm.
8cm is the same as 80mm
4 in. from back of throught to tip of tongue.
The perimeter would be 8 + 9 + 10 = 27cm
8cm is about 3 inches
128pi.
A cube has be definition has slides all of the same length, which in turn means all six faces are squares, in this case 8cm along each side. Once side would have an area of 8cm x 8cm which is 64 cm squared but you have six of them 6 x 64 cm squared is 384 cm squared
The area of the triangle with these sides is found by Heron's formula, which states that: semiperimeter = (a + b + c) / 2 Area = √(s(s - a)(s - b)(s - c)) Then: semiperimeter = (6 + 8 + 4) / 2 cm = 9 cm Area = √(9(9 - 8)(9 - 6)(9 - 4)) cm² ≈ 11.6 cm²
640 cubic centimetres
8cm x 3.2cm = 25.6cm
The volume is 1608.5cm3
32 cm² = 8cm²/2
