Which equation finds the volume of a cube with a side length of 2 n Superscript 6 units?(2 n Superscript 6 Baseline) cubed = 8 n Superscript 18 cubic units
(2 n Superscript 6 Baseline) cubed = 2 n Superscript 18 cubic units
2 (n Superscript 6 Baseline) cubed = 2 n Superscript 18 cubic units
2 (n Superscript 6 Baseline) cubed = 6 n Superscript 18 cubic units

Answers

Answer:

Volume of the cube: 8n^(18)

Step-by-step explanation:

A cube is a solid figure consisting of 6 squared faces arranged in a structure at right angle with each other.

The volume of a cube is given by:

V=L^3

where

V is the volume

L is the length of one side of the cube

In this problem, the length of the side of the cube is

L=2n^6

Therefore, the volume of the cube is

V=(2n^6)^3 = 2^3 (n^6)^3 = 8n^(18)

12 minutes she wants to jump rope for 8 minutes and play and tag for 5 minutes will Tasha have enough time explain

Answers

Tasha wants to spend a total of 8+5 = 13 minutes playing. If she has only 12 minutes, she does not have enough time. (13 is more than 12)

She wants to play tag for 5 minutes and jump rope for 8 minutes. 5 minutes, plus 8 minutes, is 13 minutes, and 13 > 12 so therefore Tasha will not have enough time to play that much.

A triangle has a base of 11 inches and a height of 8 inches.What is the area of the triangle?

A.
44 square inches

B.
64 square inches

C.
121 square inches

D.
88 square inches

Answers

A) 44 square inches

the area of a triangle is 1/2 times base times height. Therefore, because the base is 8 and the height is 11, the equation is 1/2 times 8 times 11, which is 1/2 of 88, or 44.

Hope this helped!!! :)
Formula of the Area of a triangle
=(1)/(2) × base × height
=(1)/(2) × 11 × 8
=44 in²

Answer is A. 44 square inches
