\(w\), \(x\) 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 cm\(^3\)
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 cm\(^2\) [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 \(9\tfrac{1}{2} \quad 8\tfrac{1}{2} \quad 2\) or 10 5 5 or \(6\tfrac{2}{3} \quad 6\tfrac{2}{3} \quad 6\tfrac{2}{3}\) 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
