lisa brought a tank for her hermit crab. the lank can hold 1,331 cubic inches of water and includes a top. the base of the aquarium is a square. the height of the aquarum is 11 inches. what is the lenght of each side of the base of the tank, what is the shape of the tank and what is the surface area of the tank

Answers

The formula for volume of a prism is V=(the area of the base*height). Substitute the known values so you have:
1331=11(A)
A=1331/11
A=121 in²

The base is a square, making its area is s², so you have the equation:
s²=121
s=11 in

This makes all the side lengths the same, making the tank shape a cube. 

To find the surface area of a cube, use the formula SA=6s². Substitute the known value in so you have:
SA=6*11²
SA=6*121
SA=726 in²

The final answer is that the tank is cube-shaped with a surface area of 726 in².

What two facts can you double to find 8x4?

Answers

4 is equal to 2*2 (double the 2 is 4)

We can get the value of 8*4 on two steps:
1- we multiply the 8 by 2
2- we add the result of the multiplication to itself

This is illustrated as follows:
8*2 = 16
16+16 = 32

In a right isosceles triangle, the lengths of both legs are equal. For the given iscoceles triangle, what is the value of x? (The given triangle has a hypotenuse of square root sign with 72 under it. The two legs both have x.)

Answers

it will just be 72 because both of those legs of an isosceles triangle are congruent which means that they're both X & X which is the same value
