The triangular pyramid is made of 4 congruent triangles. They all have the same shape and size, so they have the same area. The area of one triangle is

A = b*h/2
A = 5*4.3/2
A = 10.75

So four of them lead to a total surface area of 4*10.75 = 43 square meters

--------------------------

The rectangular prism has the dimensions
L = 5
W = 5
H = 4.3

The surface area is found through the formula below
SA = 2*(L*W+L*H+W*H)
SA = 2*(5*5+5*4.3+5*4.3)
SA = 136

--------------------------

So far we found that
surface area of pyramid = 43 square meters
surface area of prism = 136 square meters

Dividing the values, we get 136/43 = 3.16279 approximately. The result is not equal to 2, so Susan's statement is not correct. The prism has more than twice the surface area of the pyramid

A 240hp automobile engine delivers 195hp to the drive wheels, what is the effciency of the transmission and drive mechanism?
sweet-ann [11.9K]

Answer:

81.25%

Step-by-step explanation:

Given that :

Engine power = 240 hp

Power delivered to drive wheel = 195 hp

Efficiency = (power delivered to drive wheel / Engine power) * 100%

Efficiency = (195 / 240) * 100%

Efficiency = 0.8125 * 100%

Efficiency = 81.25%

The efficiency of transmission and drive mechanism is 81.25%
