Jennifer got a box of chocolates. the box is a right triangular prism shaped box. it is 7 in long. and the triangular base measure 2in times 3in times 4in. what is the surface area of the box of chocolates?

Answers

Answer:

$A = 68.8 inches^(2)$

Step-by-step explanation:

Given : Jennifer got a box of chocolates. the box is a right triangular prism shaped box. it is 7 in long. and the triangular base measure 2in times 3in times 4in.

a = 2

b=3

c=4

To Find : what is the surface area of the box of chocolates?

Solution: The first thing we should know is the area of the triangular base.

Triangular base area:

$A1 =√((s * (s-a) * (s-b) * (s-c)) )$

Where, s is the semi-meter of the triangle:

$s =( (a + b + c) )/( 2)$

a, b, c: sides of the triangle.

Substituting:

s = (2 + 3 + 4) /2=4.5

$A1 = √( (4.5 * (4.5-2) * (4.5-3) * (4.5-4)))$

A1 = 2.90

Then, you must know the area of each rectangle associated with each side of the triangular base.

Rectangle area 1: Ar1 = (a) * (l)

Ar1 = (2) * (7)

Ar1 = 14

Rectangular area 2: Ar2 = (b) * (l)

Ar2 = (3) * (7)

Ar2 = 21

Rectangular area 3: Ar3 = (a) * (l)

Ar3 = (4) * (7)

Ar3 = 28

Finally the surface area is: A = Ar1 + Ar2 + Ar3 + 2 * A1

A = (14) + (21) + (28) + 2 * (2.90)

$A = 68.8 inches^(2)$

Hence the surface area of the box of chocolates is

$A = 68.8 inches^(2)$
