Zara builds a model from identical cubes on a 3 × 3 square base. The table shows the base seen from above. Each number tells you how many cubes are stacked on that square. How many cubes did Zara use altogether?
A model is made from identical cubes. The table shows its base seen from above, and each number tells you how many cubes are stacked on that square. Seen from the front, the model looks like three columns of squares. How many squares tall is each column, from left to right?
The table shows the net of a cube: six squares labelled P to U, joined edge to edge in a staircase. Blank cells are empty. P and Q are side by side in the top row. R is directly below Q, with S to the right of R. T is directly below S, with U to the right of T. When the net is folded into a cube, which two faces are opposite each other?
