Answer:

Option A)724 square centimeters

Step-by-step explanation:

we know that

The surface of the prism is equal to the area of its six rectangular faces

The surface area is equal to

SA=2B+PH

where

B is the area of the base

P is the perimeter of the base

H is the height of the prism

we have

L=12\ cm

W=11\ cm

H=10\ cm

<em>Find the area of the base B</em>

B=LW

B=(12)(11)=132\ cm^{2}

<em>Find the perimeter of the base P</em>

P=2(L+W)

P=2(12+11)=46\ cm

<em>Find the surface area SA</em>

SA=2(132)+(46)(10)=724\ cm^{2}

Anastasy [175]

Answer:

97.6 cm³

Step-by-step explanation:

Volume of plastic object :

Volume of cylinder - volume of cone

From. The diagram. :

Radius, r = diameter /2 = 4/2

Volume of cylinder = pi*r²h

V = 22/7 * 2² * 8 = 100.53096 cm³

Volume of cone = 1/3*pi*r²h

V = 1/3 * 22/7 * 2² * 8

V = 2.9321531 cm³

(100.53096 - 2.9321531) cm³

= 97.598 cm³

= 97.6 cm³
