E Name each space in the space provided. You must use correct spelling and lower case letters.   Complete the net of this rectangular prism by typing the length of each side in the space provided. cm cm cm cm Complete the calculation for the surface area of the rectangular prism. SA = (bottom x2) + (front x2) + (side x2) = ( x 3) x 2 + (6 x ) x 2 + (3 x ) x 2 = + + = cm2   = ( x 9) + (10 x ) + (10 x ) + ( x 9 x )x2 SA = (base) + (back) + (front) + (triangle x2) Complete the calculation for the surface area. = + + + = cm2  Complete the following to find the length χ. You will need this answer for the next question! x2 = 152 + 2
= +
=
so, x = √289
= cm ⇦⇦Remember this number!  SA = (0.5 x 8 x ) x + (15 x ) + ( x 9) + (8x9)
= + + +
= cm2 SA = (triangle x 2) + (base) + (front) + (back) Use your previous result to find the surface area of the shape below. |
