Help me please I’m stuck on this question.

45 ft2

Step-by-step explanation:

So the total surface area= area of square part of pyramid + area of all 4 triangles

The area of square is L2 and area of triangle is 1/2*L*h

From figure L (length) is 3 and h (height) is 6

Now you just need to put these values into the formula above and your answer would be 45

Sorry for the lengthy explanation and hope this helps

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
