Answer:
(Surface Area) SA = 144
Explanation:
Since all the sides of the cube is 4 cm all of the sides will equal 16
Front and Back ( 16 + 16 ) = 32
Top and Bottom ( 16 + 16 ) = 32
Left and Right ( 16 + 16 ) = 32
32 + 32 + 32 = 96
Since it is a pyramid you need to divide it by 2 when you add all it's sides
6 • 4 = 24
All 4 sides of the pyramid are 24 besides the bottom which is the cube's top
24 + 24 = 48
24 + 24 = 48
48 + 48 = 96
Now divide it by 2 since this is a pyramid
96 / 2 = 48
96 + 48 = 144
Hope this helps dude
