**2) I**was asked to find the surface area of this.

**A)**

**My solution is :**

lxw= a

3.2x11.5= 36.8cm²

3.2x11.5= 36.8cm²

5x11.5=57.5cm²

5x11.5=57.5cm²

5x3.2=16cm²

5x3.2=16cm²

TSA= (36.8X2)+(57.5X2)+(16X2)

TSA=220.6cm²

**B)**

**My solution:**

lxw=a

4.5x10.4=46.8 cm²

4.5x10.4=46.8 cm²

12x10.4=124.8 cm²

12x10.4=124.8 cm²

12x4.5=54 cm²

12x4.5=54 cm²

TSA=(46.8x2)+(124.8x2)+(54x2)

TSA= 451.2 cm²

4) Ty is painting this storage bench for the deck. How much area does he need to paint, to the nearest hundredth of a square meter?

**My solution:**

lxw=a

0.5x1.56=0.78m²

0.5x1.56=0.78m²

0.38x1.56=0.5928m²

0.38x1.56=0.5928m²

0.5x0.38=0.19m²

0.5x0.38=0.19m²

TSA=(0.78X2)+(0.5928X2)+(0.19x2)

TSA=3.1256m²

**6) A)**Calculate the amount of material hey need to make a new cover.

**My solution:**

TSA= 2.992+2.992+0.88+0.88

TSA= 7.744m²

**B)**Waterproof material at the Fabric Warehouse is on sale this week for $24.95 per square metre. Calculate the cost to make he new cover.

**Solution:**

7.774 X 24.95= 193.96

The cost to make a new cover is $193.96.
