Find the volume and the total surface area of a cuboide whose dimension 2m, 80cm and 60cm

DENIUS [597]

Answer:

Volume= 0.96m^3

TSA= 6.56m^2

Step-by-step explanation:

Given data

Length = 2m

Width= 80cm= 0.8m

Height= 60cm= 0.6m

Volume= L*W*H

Volume= 2*0.8*0.6

Volume= 0.96m^3

TSA=2lw+2lh+2hw

TSA= 2*2*0.8+2*2*0.6+2*0.6*0.8

TSA= 3.2+ 2.4+ 0.96

TSA= 6.56m^2

Find the angle that the line through the given pair of points makes with the positive direction of the x-axis

Allisa [31]

Answer:

The answer to your question is Ф = 45°

Step-by-step explanation:

Data

A (1, 4)

B (-1, 2)

Process

1.- Find the slope of the line

formula

m = $\frac{y2 - y1}{x2 - x1}$

Substitution

m = $\frac{2 - 4}{-1 - 1} = \frac{-2}{-2} = 1$

Slope definition, is the steepness of a line and also is the tangent of the angle of the line.

tangent Ф = slope

tangent Ф = 1

Ф = tangent⁻¹ 1

Ф = 45°
