Jessica is going to paint her patio. it is made up of two rectangles. one measures 7 ft x 4 ft x 5 ft, and the other measures 10ft x 8ft x 6ft. what is the total area of her patio?

Jessica patio is made up of two rectangles.

Dimension of one rectangle which is in the shape of cuboid = 7 ft x 4 ft x 5 ft,

Dimension of Second rectangle which is also in the shape of cuboid =10 ft x 8 ft x 6 ft

→Total Area of Patio=Total  Surface Area of Cuboid having Dimension 7 ft x 4 ft x 5 ft,+ Total  Surface Area of Cuboid having Dimension 10 ft x 8 ft x 6 ft

= 2 ×[7×4+4×5+5×7]+2×[10×8+8×6+10×6]

=2×[28+20+35]+2×[80+48+60]

=2×83 +2×188

=166+376

=542 square feet

Upper face of larger cuboid is partially covered , with smaller cuboid.

Area of Lower face of smaller cuboid =7 ×4=28 square feet

Total Area of patio = 542- (Area of lower face of smaller cuboid)

  = 542 - 28

  =514 square feet

it will be a cylinder. with a diameter of 8 and 4 single pieces high
