\(w\), \(x\) and \(y\) are different whole numbers.
The total length of all the edges of the cuboid is 80 cm
The volume is greater than 200 cm3
Work out one possible set of values for \(w\), \(x\) and \(y\). [2 marks]
(b) Here is a solid cube.
Circle the expression for the total surface area in cm2[1 mark]
\(36a\)
\(54a\)
\(36a^2\)
\(54a^2\)

any order B1 answer of three positive numbers in any order with sum 20 eg 17 2 1 or \(9\dfrac{1}{2}\) \(8\dfrac{1}{2}\) 2 or 10 5 5 or \(6\dfrac{2}{3}\) \(6\dfrac{2}{3}\) \(6\dfrac{2}{3}\) or correct equation in \(w\), \(x\) and \(y\) eg \(4w + 4x + 4y = 80\) or \(w + x + y = 20\)
Additional guidance
Ignore attempts to work out the volume or surface area eg 10 5 5 volume calculated as 500
