Answer:

(a) 40 units

Step-by-step explanation:

32/16=2

20 times 2=40

Answer:

A

Step-by-step explanation:

Since square pyramids A and B are similar, they need to have similar lengths.

Pyramid B's lengths are 2 times larger than that of pyramid A.

Pyramid A: 16 units, 16 units, 20 units.

                     *2            *2           *2

Pyramid B: 32 units, 32 units, ? units

So, the missing side length has to be 20 *2 = 40 units.
