Part A (Preliminary): Consider a 30cm square of tinplate. (a) Determine the volume of the cake tin if a 4cm square is cut from each corner and the sides folded to form the tin. (b) Determine the volume of the cake tin if the following squares are cut from each corner of the tinplate: (i) 2cm (ii) 5cm (ii) 8cm (c) Given the length of each side of the square tinplate is 30cm, show that the volume of the cake tin car be expressed as V(x) = 4x3 – 120x2 + 900x cm³, where x (cm) is the size of the square cut from each corner. 30 cm
