Answer:

  • length: 2 cubes
  • width: 1 cube
  • height: 2 cubes
  • volume: 4 cubes

Step-by-step explanation:

We assume in this context that a "1/4 unit cube" is a cube that is 1/4 unit on a side. When the "unit" is "inches", then the "1/4 unit cube" is a cube that is 1/4 inch on a side.

It should not take too much thought to realize that a dimension that is 1/2 = 2/4 inches will be 2 cubes long. A dimension that is 1/4 inch will be 1 cube long.

Then the 1/2 by 1/2 by 1/4 prism will have dimensions in "cubes" of ...

  2 cubes × 2 cubes × 1 cube

As with any rectangular prism volume calculation, the volume is the product of the dimensions:

  V = LWH = (2)(1)(2) = 4 . . . cubes

_____

For this prism, it should not be too difficult to see that if you stack 2 smaller cubes on top of two smaller cubes, the overall dimensions of that will be 1/2 inch wide by 1/2 inch high by 1/4 inch deep.

_____

<em>Additional comment</em>

Which dimensions you call length, width, and height are irrelevant, as each is interchangeable with any other in the formula for volume. Here, I have elected to call height the vertical dimension, length the left-right horizontal dimension, and width the front-back dimension. You are welcome to choose an assignment of names to dimensions that suits your taste (or that of your grader).

Answer:

<u>4</u>

Step-by-step explanation:

Hi so basically you just convert the inches to decimals so

0.5 x 0.5 x 0.25 = 0.0625

Use a calculator to convert 0.0625 into fraction which is \frac{1}{16}

Multiply \frac{1}{4} by 3 = \frac{1}{64}

Then multiply \frac{1}{16} by \frac{1}{64} = 4

Soo that was probably very confusing, but I hope it helps! :)

Plz click the Thanks button, I rrly appreciate it!

Answer:

Triangle APB is an isosceles triangle ⇒ 3rd answer

Step-by-step explanation:

* Lets explain the how to solve the problem

- ABCD is a square

∴ AB = BC = CD = AD

∴ m∠A = m∠∠B = m∠C = m∠D = 90°

- DPC is equilateral triangle

∴ DP = PC = DC

∴ m∠DPC = m∠PCD = m∠CDP = 60°

- In the Δs APD , BPC

∵ AD = BC ⇒ sides of the square

∵ PD = PC ⇒ sides of equilateral triangle

∵ m∠ADB = m∠BCP = 30° (90° - 60° = 30) ⇒ including angles

∴ Δs APD , BPC are congregant ⇒ SAS

- From congruent

∴ AP = BP

∴ Triangle APB is an isosceles triangle

The diagram shows a square with perimeter 20 cm.
olga_2 [115]

The percentage of the area inside the square that is shaded is 55%.

<h3>What is the perimeter of the square?</h3>

Given:

The perimeter of the square is 20Cm

Each side of the square is = 5Cm

Area = ( Length x Width )

(5 x 5) = 25 =Area

Area = 25

Area of triangle 1 = (1/2) x 5 x (5 - 3) = 5 cm²

Area of triangle 2 = (1/2) x 5 x (5 - 3.5) = 6.25 cm²

Area of shaded portion = 25 - (5 + 6.25) = 13.75 cm²

Percentage of shade portion

= (13.75 cm² / 25 cm²) x 100%

= 55%

The percentage of the area inside the square that is shaded is 55%.
