Explanation:

the top surface area of the water is 25 x 15 = 375 cm².

the water in contact with the sides is (25 + 15) x 2 x 10 [depth] = 800 cm².

the base area of the water is 25 x 15 = 375 cm².

∴ the wet area of the tank surfaces = 1175 cm².

and the total water surface area [top, bottom and sides = 1550 cm².
