We know that [volume of a square pyramid]=area of the base*height /3 area of the base=3*volume/height volume=245 in³ height=15 in area of the base=3*245/15-------> 49 in²
the area of the base is a square so area=b²---------> b=√area---------> b=√49-------> b=7 in
the answer is T<span>he length of one side is 7 in</span>
