What is the surface area

424 cm²

Step-by-step explanation:

8 x 11 = 88 = 1 side

88 x 2 = 196 = 2 sides

11 x 6 =66 = 3 sides

66 x 2 = 132 = 4 sides

8 x 6 = 48 = 5 sides

48 x 2 = 96 = 6 sides

196 + 132+ 96 = 424

The distance between -66 and -34 is 32 units.  To find the speed in 5 minutes, you will divide the distance of 32 units by the time it took to travel that distance (5 minutes).  You can write it as a rate 32 units/5 mins.  The speed is 6.4 units per minutes when you divide it out.
