Divide the box into two parts for easy way answer
For cube:-
TSA
Cancel one side area
For triangular pyramid:-
Area of one base
- 0.5(Base)(Height)
- 0.5(12)(15)
- 6(15)
- 90cm^2
Area of four sides=90(4)=360cm^2
<h3>Total surface area:-</h3>

Step-by-step explanation:
angle 3

angle 4

angle 2 is 49
angle 1

W^2+5w-66=0
Factor
(w+11)(w-6)=0
w+11=0
w=-11 (not possible - cant have negative length
w-6=0
w=6
L(6)=66
L=11
Width = 6
Length = 11
