Step-by-step explanation:
The box is in the shape of a cuboid:
Surface area of the cuboid = 2(L*W+W*H+H*L)
Length(L)=20.1 m
Width(W)=6.8 m
Height(H)=7.4 m
Surface area:

The surface area of the box is 
Answer:
2q^6
Step-by-step explanation:
23. because there is a 90 degree angle and then the 67 degree angle, and triangle law says that all angles add up to 180.
Distributive property: 3x3 and 3xn
So... 9x3n which becomes
27n
