What is the total surface area of a right rectangular prism with a base of 2 cm by 3 cm and a height of 6 cm? A) 13 cm2. B) 72 cm2. C) 113 cm2. D) 226 cm2.

Answers

Answer 1
Answer:

Answer:=72\ cm^2,

Step-by-step explanation:

The total surface area of a right rectangular prism is given by :-

\text{Total surface area}=2(lw+wh+hl), where h is height, w is width and l is length of the prism.

Given: Height = 6 cm

Dimensions of base =  2 cm by 3 cm

Now, the total surface area of a given right rectangular prism is given by :-

\text{Total surface area}=2(2\cdot+3\cdot6+2\cdot6)=2(6+18+12)=2(36)=72\ cm^2,
Answer 2
Answer:  (L · W · 2) + (perimeter of the base · height). For this prism, that's (2 cm · 3 cm · 2) + (2 cm + 2 cm + 3 cm + 3 cm) · 6 cm. This is (12 cm2) + (10 cm · 6 cm) = 72 cm2.

one side of a square is 10 units which is greater the number of square units for the area of the square or the number of units for the perimeter explain

Answers

The area of the square would be 10 times 10 because you multiply length and width. The perimeter of the square would be 10 times 4 because you add all four sides. 10 times 10 is 100, which is greater than 10 times 4 which is 40.

The diameter of a circle is 28 inches. Find the circumference and area. Use 22/7 for pie

Answers

The circumference of the circle is 88 inches, and the area is 616 square inches.

Here, we have,

To find the circumference and area of a circle, we can use the formulas:

Circumference = π × Diameter

Area = π × (Radius)²

Given that the diameter of the circle is 28 inches, we can calculate the radius by dividing the diameter by 2:

Radius = Diameter / 2

           = 28 inches / 2

           = 14 inches

Using the value of π as 22/7, we can now calculate the circumference and area:

Circumference = π × Diameter

                         = (22/7) × 28 inches

                        = 88 inches

Area = π × (Radius)²

         = (22/7) × (14 inches)²

        = 616 square inches

Therefore, the circumference of the circle is 88 inches, and the area is 616 square inches.
