[surface area ]=2*[area of the base]+[perimeter of the base]*height area of the base=10*8.7/2-----> 43.5 cm² perimeter of the base=10*3----> 30 cm height of the prism=15 cm [surface area ]=2*[43.5]+[30]*15------->537 cm²
the answer is <span>the approximate surface area of the prism is 537 cm</span>²
