Answer:

254 yds²

Step-by-step explanation:

There are 6 faces of the prism we need to calculate the area of for a rectangular prism.

The base and top of the prism measure 9x7 yards each, so there are two faces with an area of 63 yds² (9 x 7 = 63)

The sides of the prism measure 4x7 yards each, so there are two faces with an area of 28 yds² (4 x 7 = 28)

The front and back face of the prism measure 9x4 yards each, so there are two faces with an area of 36 yds² (9 x 4 = 36)

The total surface area is

2(63) + 2(28) + 2(36) = 254 yds²

Answer:

D) 6.79 x 10^7

Step-by-step explanation:

Company D has the greatest revenue because it is multiplying by 10 to the power of 7 which is the same as multiplying by 10 seven times. The least revenue is company C because it is only multiplying by 10 to the power of 4 which is the same as multiplying by 10 4 times.

6.8 x 10^7 = 68,000,000

9 x 10^4 = 90,000

68,000,000 - 90,000 = 67,910,000.

Convert this back into standard form to get 6.79 x 10^7
