#### Storyboard Text

• Hi Charlotte! what are you doing?
• HI Tina! i was just preparing the cake for the party this evening.
• Do you want any help from me?
• Yes i need a bit of your help... I want to decorate the cake's outer line with some chocolate Chips but i don't know how much chocolate chips I need..
• Ok so let me help you... So first of all you have to tell me what is the shape of your cake.
• Yes so the shape of my cake is a rectangle.
• Ok now tell me the dimensions of your cake and the size in centimetres of the wafers
• Yes so the dimensions of my cake 12 cm length and 6 cm width and the size of the wafers in centimetres is 6 cm.
• Ok so 6x2 = 12 and 6 x 1 is 6 so 12 + 6 is 18 and as there are 2 lengths and two breadths we will multiply 18 into 2 which is 36 so 36 is the total centimetres of wafers and then as each wafer is of 6 centimetres , we will divide which equals to 6 so 6 wafers are needed for the boundary of the cake.
• Oh thank you so much Charlotte.. Yes sure I will be there.. Bye and take care!
• Thank you so much Tina for helping me out and do remember to come to the party at 6:00 pm... Bye and take care!
