Question

a block of wood is a cube and has the dimensions shown in the
part a
find the volume of the block of wood.
answer:
cm³
part b
find the surface area of the wooden block.
a 200 cm²
b 324 cm²
c 150 cm²
d 230 cm²

Explanation:

Step1: Recall cube volume formula

Volume formula: $V = s^3$, where $s=5\ \text{cm}$

Step2: Calculate cube volume

$V = 5^3 = 125$

Step3: Recall cube surface area formula

Surface area formula: $SA = 6s^2$, where $s=5\ \text{cm}$

Step4: Calculate cube surface area

$SA = 6\times5^2 = 6\times25 = 150$

Answer:

Part A: $125\ \text{cm}^3$
Part B: C. $150\ \text{cm}^2$
