which expression is equivalent to doesn't give enough info.
Answer:
10 cm²
Step-by-step explanation:
74 088 is the cubed of one side. So you would do ![\sqrt[3]{74088}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B74088%7D)
which is 42. So one side of the cube is 42. To find the surface area, you would do 6(42x42) which would give you 10584. Remember to put cm²
The Laplace transform of the given initial-value problem
