Explanation with steps:
= 1/2 x a x t
= 1/2 x 5 x 12
= 30 cm²
The length of the triangle side :
= √ (5² + 12²)
= √ (25 + 144)
= √ (169)
= 13 cm
Around the base :
= 5 + 12 + 13
= 30 cm
Prism surface area = (2x the base area) + (around the base x the height of the prism)
= (2 x 30) + (30 x 16)
= 60 + 480
= 540 cm²
