| Hey, yeah i'm also a seventh grader. and the formula is V=Bh. to get the area of the base you divide it into 6 triangles. divide one of those triangles in half to make two right triangles and use the pythagorean theroem to get the last side. then from there find the are of one right triangle and double it to get the area of one of the equilateral triangles. that area multiplied by 6 will get you the area of the base. |
