Answer:
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 .
