Find the surface area of this prism.
Round to the nearest tenth.

The answer is 493.3

Step-by-step explanation:

6.72 x 12.7 x 5.78 = 493.28872

And 493.28872 rounded to the nearest tenth is 493.3 because the original number in the tenth place is 2 and then the digit before that is 8 which in this case is your rounding digit. Round up If the number is greater than 5 and round down if its less than 5. In this case its greater than 5 to that leaves you with 28 so now you have 493.28, 28 rounded to the nearest tenth is 30 and just take the 0 away, as if it didn't exist.

395.2 cm²

Step-by-step explanation:

This is used to find the surface area of rectangular prisms:

Surface Area = 2(width×length + hight×length + hight×width)

Surface Area = 2(5.78×12.7 + 6.72×12.7 +6.72×5.78)

Surface Area = 395.1832

395.1832 cm² rounded to the nearest tenth is 395.2 cm²
