    If a cube has total surface area is 2400m² then how much L liquid store in this cube tank

    \sf{\red{\underline{\underline{\purple{Solution:-}}}}}

    • Let length of a side of a cube = xcm
    • T.S.A = \sf 6a^2—equ(1)

    ★ T.S.A= 2400 \sf m^2----equ(2)

    ★ According to question

    ★ equation (1) = equation (2)

    \sf→ 6a^2=2400\\\sf→ a^2=\frac{2400}{6}\\\sf→ a^2=400\\\sf→ a=\sqrt{400}\\\sf→ a=20cm

    We have to find out liquid store in a cube tank or volume =?

    \sf→ liquid\: contain \:or\:volume= a^3\\\sf→ liquid\: contain \:or\:volume = 20×20×20\\\sf→ liquid\: contain \:or\:volume= 8000m^3

    Hence,

    capacity of a cubic tank is \sf 8000 \:litre

    Answer:

    8000L

    Step-by-step explanation:

    tsa of cube is 6a2

    6a2=2400m2

    a2=2400/6

    a2=400

    a=20m

    volume = a3

    (20)^3=8000L
