A rectangular prism measures 8 inches in width,12 inches in length and 4 inches in height. What is the surface area of the prism? Enter your answer In the box.

352

Step-by-step explanation:

A = 2(wl+hl+hw) = 2(8 · 12 + 4 · 12 + 4 · 8) = 352

A=352in2

A=2(wl+hl+hw)=2·(8·12+4·12+4·8)=352in²

Step-by-step explanation:

surface area of rectangular prism = 3(area of rectangle)+ 2(area of triangle)

=3*(4*12)+2*(1/2*8*4)

=3*48+2*16

=144+32

=176sq.in

the data of the detroit pistons in numerical order from least to greatest is 0.30, 0.37, 0.55, 0.62, 0.69, 0.72, 0.73, 0.75, 0.77, 0.78, 0.80, 0.81, 0.81, 0.83, 0.84, 0.89

the data of the miami heat in numerical order from least to greatest is 0.50, 0.50, 0.56, 0.57, 0.67, 0.72, 0.72, 0.72, 0.75, 0.75, 0.76, 0.81, 0.82, 0.90, 1.00, 1.00

the detroit pistons median : 1.52

the miami heat median: 1.47

the iqr of this data is 0.05

probability for j is 1/4

while

a is 1/6

For this case we have that the surface area of the prism is given by:

[tex]SA = A_ {l} + 2B[/tex]

Where:

[tex]A_{l}[/tex]: Is the lateral area

B: It is the area of the base

[tex]A_ {l} = P.h[/tex]

Where:

Q: It is the perimeter of the base

h: It's the height

[tex]A_ {l} = 40 * 4\\A_ {l} = 160 \ in ^ 2[/tex]

On the other hand:

[tex]B = 12 * 8\\B = 96 \ in ^ 2[/tex]

So, we have:

[tex]SA = A_ {l} + 2B\\SA = 160 \ in ^ 2 + 2 * 96 \ in ^ 2\\SA = 352 \ in ^ 2[/tex]

[tex]SA = 352 \ in ^ 2[/tex]

The surface area of prism = 352 square inches

Step-by-step explanation:

Formula:-

Surface are of rectangular prism = 2(lb + bh + lh)

l - Length of prism

b - width of prism

h - Height of prism

It is given that,a rectangular prism measures 8 inches in width, 12 inches in length, and 4 inches in height.

To find the surface area of prism

l = 12 inches

b = 8 inches

h = 4 inches

surface area = 2(lb + bh + lh) = 2(12*8 + 8*4 +12*4)

= 2(96 + 32 + 48) = 352 square inches.

Therefore the surface area of prism = 352 square inches

s= 2( lw + hw+ hl)

298

Step-by-step explanation:

w = 8inched

l=12inches

h=4inches

s = 2 ((12×8)+(4×8)+(4×12))

=2 (96+32+48)

= 2 (149) =298
