Explanation

To find the total surface area (TSA) of the box:

TSA = 2(lb + bh + hl)

Given length (l) = 5 cm, breadth (b) = 2 cm, and height (h) = 3 cm:

TSA = 2(5_2 + 2_3 + 3*5)

= 2(10 + 6 + 15)

= 2(31)

= 62 cm²

Explanation

A simile compares two unlike things using "like" or "as".

"She ran like the wind" compares her speed to the wind using "like", making it a simile.

Explanation

In Scratch programming, an event is something like clicking a sprite or pressing a key, and the program responds to it by running certain code.

Events help make Scratch projects interactive and dynamic.

Explanation

To find the area of the carpeting part, we need to find the area of the inner rectangle (without carpet) and subtract it from the total area.

Length of inner rectangle = 7.8 - 22.3 = 3.2 m

Width of inner rectangle = 6.5 - 22.3 = 1.9 m

Area of the room = 7.8 * 6.5 = 50.7 m^2

Area of inner rectangle = 3.2 * 1.9 = 6.08 m^2

Area of carpet = Total area - Inner area

= 50.7 - 6.08

= 44.62 m^2

Explanation

The phrase "in his ear" modifies the verb "whispered", specifying where/how the action occurred.

In grammar, phrases that modify verbs are classified as adverb phrases.

Explanation

Transitive verbs require a direct object to complete their meaning (e.g., "She kicked the ball").

The subject is needed to start the sentence, but it is not specifically required by transitive verbs to complete their meaning.

Explanation

Explanation

The sentence is a second conditional (imaginary/unreal situation in the present), using "if + past tense" and "would + base verb".

Since it says "if the weather were good", the correct structure is: "We would play football."

Explanation

Given:

log₈₁ 9 = x

We can rewrite this in exponential form:

81^x = 9

Since 81 = 9², we can rewrite:

(9²)^x = 9

9^(2x) = 9¹

Equating the exponents:

2x = 1

x = 1/2

x = 0.5
