Question

A fish tank is in the shape of an open glass cuboid 30cm deep with base 16cm by 17cm external measurement thickness 0.5cm mass 3

Answer 1

Answer:

hey mate here is ur answer

Step-by-step explanation:

. The problem has one cuboid inside another. The bigger cuboid is the tank and its glass, the smaller cuboid is the volume inside the tank. The problem gives the dimensions of the overall tank so the

. Volume of tank and glass=VT&G=30*16*17

. Volume inside tank is difficult as it depends on how the tank is constructed. Do the sides sit on the base or do the sides surround the base. Where the sides abut to each other is one side shortened but not the other are are they all shortened equally. Each configuration will give a different answer.

. I will opt for the base abutting the lower edge of the sides and the sides abutting each other alternately. So the inner dimension are (16–1/2–1/2) by (17–1/2–1/2) by (30–1/2) or 15 by 16 by 29..5 . So Tank Volume=TV=15*16*29.5

. So tank Capacity is TV

. Glass volume = VT&G - TV

. Mass of Tank = Glass Volume*3

. hope it was helpful thank you
