a fish tank is in the shape of an open glass cuboid 30cm deep with a base 16cm by 17cm, these measurements being external. if the glass is 0.5cm thick and its mass is 3g/cm cube. find the capacity of the tank in litres​

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
