1- Find the surface area and volume of each solid figure.2-Show the equations you used.PLEASE HELP!!!!!!! 20 points

Answer:Volume Figure 1 = 56 cube units figure 2 = 60 cube units figure 3 =72 cube units Surface area Figure 1 = 100 square unitsfigure 2 = 104 square unitsfigure 3 =108 square unitsStep-by-step explanation:From the all figure we can see that each figure made up of unit cubesFigure 1Surface area Large cuboid portion =2 x (6 x 2 ) +  (6 x 4) + 2 x(4 x 2) + 16   = 24 + 24 + 16 + 16 = 80 unit squareSmall cuboid portion = (4 x 2) + (2 x 2) + (4 x 2) = 8 + 4 + 8 = 20Total surface area = 80 + 20 = 100 unit squareVolumeSmall cuboid = 4 x 2 = 8Large cuboid = 6 x 4 x 2 = 48 cube unit Total volume = 48 + 8 = 56 cubs unitsFigure 2Surface area Total surface area =24 + 18 + 36 + 20 + 6 = 104 unit squareVolumeSmall cuboid = 6 x 2 = 12Large cuboid = 6 x 4 x 2 = 48 unit square Total volume = 48 + 12 = 60 cube unitsFigure 3Surface area Total surface area = 48 + 36 + 24 = 108 square units VolumeTotal volume = 6 x 4 x 3 = 72 cube units
