Solve the problem. how many square centimeters of glass does it take to make the bottom and sides of a cube-shaped aquarium with an edge lenght of 38 cm?

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 .

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
