Question

Is this correct? If it isn't, please tell my why.

Answer 1

Answer:

When I solve it , I got the answer not the same with you.

( i ) The lateral area of the prism is 204.

( ii ) The total surface area of the prism is 744.

Step-by-step explanation:

( i )  We got that answer because we multiply 17 cm with 12 cm.

        ( 17 x 12 )

       Because it ask only ask for the lateral area which is length and width.

       Lateral means side or side so it is length and width not height and

       width/length.

( ii )  We got that answer because first step we multiply 17 cm with 12 cm.

       We also have to multiply the gotten answer with 2.

       Second step, we multiply 12 cm with 7 cm. Almost gonna forgot,

        we also have to multiply the gotten answer with 4. Then, add the first

        step and second step to make the total surface area.

         = ( 17 x 12 x 2 ) + ( 12 x 7 x 4 )

         = ( 204 x 2 ) + ( 84 x 4 )

         = 408 + 336

         = 744
