What is surface area of an object?
The surface area is the total area of the surface of a 3-dimensional object. To find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.
The surface area of the prism is,
Surface area of the prism = 2(0.5×1.5×2) + (2.5×10) + (1.5×10) + (2×10)
= 3m² + 25m² + 15m² + 20m²
= 63 m²
Hence, the surface area of the triangular prism is 63 m².
