    It takes 7,220 sq cm of glass to make the bottom and sides of a cube-shaped aquarium.

    Step-by-step explanation:

    The length of the edge of glass square = 38 cm

    Now, to complete 1 cube aquarium the number of glass squares required

    = 1 base square + 4 sides at 4 sides (TOP IS OPEN)

    = 5 glass squares

    Now, area of one glass sq. = EDGE x EDGE

    = 38 cm x 38 cm = 1,444 sq cm

    So, the area of 5 glass squares = 5 x (AREA OF EACH SQ.)

    = 5 x (1,444 sq. cm) = 7,220 sq cm

    ⇒The total surface area of the cube shaped aquarium = 7,220 sq cm

    Hence, it takes 7,220 sq cm of glass to make the bottom and sides of a cube-shaped aquarium.
