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>
180/3 = 60 and I believe x is 60/2 = 30
42 is the number because...
42 ÷ 6 = 7
42 ÷ 7 = 6
