AN OPEN WATER TANK WITH LENGTH 20CM AND WIDTH 15CM HOLD 4.8 LITER OF WATER .CALCULATE THE HEIGHT OF WATER LEVEL IN THE TANK AND THE TOTAL SURFACE AREA OF THE CUBOID IN CONTACT WITH THE WATER

Answer 1

since 1L = 1000 cm^3, if the height ish, then we know that

(20)(15)(h) = 4800
h = 16

So, the wet surface area is

bottom + 2 long sides + 2 short sides
= 20*15 + 2*16(20+15)
= 1420 cm^2
