5 single rolls  or 3 double rolls.

Step-by-step explanation:

Ignoring doors and windows, we need to find the lateral surface ares.  We are not papering the ceiling or floor.

The lateral surface areas = P*h

                                            = 2(l+w) * h

                                             = 2(10+12) * 8  

                                             = 2(22)*8

                                              =352  ft^2

A single roll covers 72 ft^2 so we divide the number of ft^2 that we need (352^2) by the amount of a single roll

352/72 =4.88888(repeating)

Rounding up since we need to buy in full rolls.

We will need 5 rolls

Assuming a double roll will cover  twice that of a single roll

2*72 = 144 ft^2

Take 572/144 =2.4444444

Rounding up since we need to buy in full rolls.

We will need to buy 3 double rolls
