Length and 1 cm height are painted red. What is the total surface area of the painted block?

The total surface area of the cuboid is given by the formula: 2(length x breadth + breadth x height + height x length).

In this case, the length is 6 cm, the breadth is 4 cm, and the height is 1 cm.

Plugging these values into the formula, we get:
2(6 x 4 + 4 x 1 + 1 x 6) = 2(24 + 4 + 6) = 2(34) = 68 cm².

Therefore, the total surface area of the painted block is 68 cm².
