For my maths today I had to complete an IXL task. This task was to identify the volume of cubes and rectangular prisms, For this IXL question it was asking for the value of u.
To find the value you have to know your times tables (You have to times the width by the length and then times the number you recieved by the height 4x4x4 etc.) The answer for this question would have been 6 because 6x6x6= 216!
