a. the base cm is 384cm
b. the lateral area is 692cm
c. the surface area is 740cm
d. the area of each congruent face is 264cm

Option B. The Lateral area is 692 cm2

Step-by-step explanation:

Verify each statement

case A) The area of the base  is 384 cm2

The statement is False

Because

The area of the base is

case B) The Lateral area is 692 cm2

The statement is True

Because

we know that

The lateral area is equal to the area of its three triangular lateral faces

so

case C) The surface area is 740 cm2

The statement is False

we know that

The surface area is equal to the lateral area plus the area of the base

so

we have

substitute

case D) The area of each congruent face is 264 cm2

The statement is False

The area of  each congruent face is equal to

$20.01
