Question

the height of one side of the pyramid is 10. the base is 7×7. What is the surface area ?

Answer 1

49 because that's the base then if the side of the base is 7 then its 7×10 which is 70 divided by 2 since its a triangle then 35 × 4 because 4 sides which is 140 plus 49 because surface area of base so 189 is your answer
