Answer:
1. 617.5 cm³
2. 335.6 in³
3. 151.6 m³
4. 3479.1 ft³
Step-by-step explanation:
1.
B1: 19.5 × 9 = 175.5
B2: 6 × 13 = 78
sqrt(B1 ×B2) = 117
h = 5
Volume = ⅓ × 5 × [175.5 + 78 + 117]
617.5
2.
B1: 3.14 × 4.5² = 63.585
B2: 3.14 × 3² = 28.26
sqrt(B1 ×B2) = 42.39
h = 7.5
Volume = ⅓ × 7.5 × [63.585 + 28.26 + 42.39]
335.5875
3.
B1: ½(8+12) × 6 = 60
B2: ½(3+4.5) × 2.25 = 8.4375
sqrt(B1 ×B2) = 22.5
h = 5
Volume = ⅓ × 5 × [60 + 8.4364 + 22.5]
151.5625
4.
B1: 3.14 × 12² = 452.16
B2: 3.14 × 7² = 153.86
sqrt(B1 ×B2) = 263.76
h² = 13² - (12-7)²
h² = 13² - 5²
h² = 144
h = 12
Volume = ⅓ × 12 × [452.16 + 153.86 + 263.76]
3479.12

Answer:
∠C and ∠R
Step-by-step explanation:
The ASA postulate represents angle / side / angle
where the included side is the side between the vertices of the two angles.
∠H and ∠I and the sides HC and IR are the AS
The required angles would be ∠C and ∠R for ASA

Final answer:
The volume of a cube is calculated by multiplying its length, width, and height. Given the measurements with length of 5 cm, width of 16 cm, and height of 10 cm, their product equals 800 cubic centimeters.
Explanation:
The volume of a cube or a cuboidal object can be calculated using the formula Length x Width x Height. In this case, the given measurements are length is 5 cm, the width is 16 cm, and the height is 10 cm.
So, by substituting these values into the formula, we get:
Volume = Length x Width x Height
= 5 cm x 16 cm x 10 cm
= 800 cubic cm
So, the volume of the cube with the given measurements is 800 cubic cm.

What are Arithmetic operations?
Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
Given that ken grew 4/5 of an inch last year
And Sang grew 3/8 of an inch
Converting the fraction into decimals
⇒ 3/8 = 0.375
⇒ 4/5 = 0.8
ken grew 0.375 of an inch last year
And Sang grew 0.8 of an inch
Take those two figures and subtract the smaller amount from the larger number.
⇒ 0.8 - 0.375
⇒ 0.425
So, ken grew 0.425 of an inch more than sang
Hence, ken grew 0.425 of an inch more than sang
