The solids are similar. find the surface area s of the red solid. round your answer to the nearest tenth.

The ratio of surface area is the square of the ratio of linear dimensions.

Red Area = (6/8)^2 * 154 yd^2 = 86 5/8 yd^2

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
