A cuboid has edges measuring 4 cm, 5 cm, and 6 cm. What is its total surface area?

Explanation

The surface area of a cuboid is calculated using the formula 2(lw + lh + wh). Substituting the values: 2(4×5 + 5×6 + 4×6) = 2(20 + 30 + 24) = 2(74) = 148 cm². Therefore, the correct surface area is 148 cm².
