Question

What is the surface area of the pyramid shown to the nearest whole number? The diagram is not drawn to scale.

A) 21ft^2
B) 48 ft^2
C) 57 ft^2
D) 105 ft^2

Is the answer 57? I wasn't really sure what formula to use for this question so if there's another formula I should use that would mean so much to me. Thank you.

Answer 1

Any help would be wonderful! :)

Answer 2

@Michele_Laino Sorry for pestering you again, ha. But do you know the formula for this? I'm not sure the one I used was the correct one.

Answer 3

total Surface \(S_T\), is:
\[{S_T} = \left( {\frac{{3 \times 8}}{2}} \right) \times 4 + \left( {3 \times 3} \right) = ...?\]

Answer 4

57, correct?
