Question

6. In the figure opposite, PABCD is a pyramid whose base is the square ABCD and whose edges are such that PA = PB = PC = PD. Suppose that M is the midpoint of PC and that 2BM D = 90 °. We remove from the PABCD pyramid the base pyramid triangular MBCD by cutting along the triangle defined by points M, B and D. The resulting solid PABMD has a volume of 288. What is the length from AB?​

Answer 1

Step-by-step explanation:

In the figure opposite, PABCD is a pyramid whose base is the square ABCD and whose edges are such that PA = PB = PC = PD. Suppose that M is the midpoint of PC and that 2BM D = 90 °. We remove from the PABCD pyramid the base pyramid triangular MBCD by cutting along the triangle defined by points M, B and D. The resulting solid PABMD has a volume of 288. What is the length from AB
