Work out the surface area of a cuboid 2cm by 5cm by 3cm?

The formula to find the surface area of a cuboid is 2(a^2+b^2+c^2) (^2 is just to the second power or squared or whatever you call it but it cant supersript so it looks messy sorry) so in this instence it would be 2(2^2+5^2+3^2) which equals 76

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
