Answer:

A=2 square units

Step-by-step explanation:

It is given that square has the hypotenuse of a right triangle as one of its sides.

Thus, in order to find the hypotenuse of the square, we use the Pythagoras theorem, that is

c^2=a^2+b^2

⇒c^2=(1)^2+(1)^2

⇒c^2=1+1

⇒c^2=2

⇒c=\sqrt{2}units

Therefore, the length of the hypotenuse will be {\sqrt{2}}.

Now, since square has all the sides of equal measure, therefore the measure of the sides of the square will be {\sqrt{2}}units.

Now, Area of square is given as:

A=(side)^2

A=(\sqrt{2})^2

A=2 square units

Thus, the area of square is 2 square units.

Since the legs of the triangle are 1 and 1 the hypotenuse would be 1 also. And since squares have equal sides you know that every other side of the square are 1. The algorithm for area is base times height. So 1 times 1 is 1 unit squared.<span />

A cube of sides 10cm was cut across to obtain a prism. Calculate the surface area of the prism and the volume of the prism
hodyreva [135]

Answer:

Part A

The volume of the triangular prism is 500 cm³

Part B

The total surface area of the prism is approximately 441.42 cm²

Step-by-step explanation:

The given details are;

The dimensions of the side length of the cube, s = 10 cm

The shape the cube was cut across to obtain = A prism

Part A

Whereby the prism obtained is a triangular prism, we have;

The cube can be cut in half to form a triangular prism

The volume of each triangular prism obtained = (1/2) × The volume of the cube

∴ The volume of the triangular prism = (1/2) × (10 cm)³ = 500 cm³

Part B

The height of the prism, h = 10 cm × sin(45°) = 5·√2 cm = (1/2) × The base width of the prism

The triangular cross sectional area of the prism, A₁ = 5·√2 × 5·√2 = 50

The square cross sectional area, A₂  = 10 × 10 = 100

The cross sectional area of the base, A₃ = 10·√2 × 10 = 100·√2

The total surface area of the prism, A = 2·A₁ + 2·A₂ + A₃

∴ A = 2×50 + 2×100 + 100·√2 = 300 + 100·√2 ≈ 441.42

The total surface area of the prism, A ≈ 441.42 cm²
