the surface area = 42cm²
Step-by-step explanation:
We apply the formula for surface area of rectangular prism:
Area = l * w + l*h + l* w + h * l + w * h + w * h
Area = 3cm × 2cm + 3cm×3cm + 2cm× 3cm + 3cm×3cm + 3cm × 2cm + 3cm × 2cm
Area = 6cm² + 9cm² + 6cm² + 9cm² + 6cm² + 6cm²
Area = 42cm²
Therefore, the surface area = 42cm²
