Anettt [7]2 years ago
8 0

Answer:

SA = 202

Step-by-step explanation:

Surface area = Sum of all 6 areas of each side of the cuboid

SA = 2 (4·5 + 5·9 +9·4), because there are 2 of each kind of sides

SA = 2 (20+ 45 + 36)

SA = 2·101

SA = 202

there is $3080 in the math department fund. They need to deposit enough money in the fund to pay for a shipment work $2800, and
tiny-mole [99]

Answer:

3080+d > = 3300

Step-by-step explanation:

The first question to ask is how much money do they need in the fund?

They need the shipment costs plus the future shipment costs

2800+500 = 3300

They have 3080

Let d = how much they need to deposit

How much they have plus how much they need to deposit must be greater than or equal to how much they need.

3080+d > = 3300
