Step-by-step explanation:
To find the total surface area of the aquarium, you need to calculate the sum of the areas of its six faces.
The external dimensions of the cuboid are:
Length (l) = 80 cm,
Breadth (b) = 30 cm,
Height (h) = 40 cm.
The surface area (S.A.) of a cuboid is given by the formula:
[tex] \large{ \red{2(lb + bh + lh)}} \\ [/tex]
Let's substitute the values:
[tex]2 \bigg[(80 \times 30) + (30 \times 40) + (40 \times 80) \bigg] [/tex]
