Question

4. The figure shows a glass block made up of
a rectangular prism with dimensions 56 cm by
24 cm by 40 cm and one-quarter of a cylinder
with a base radius of 24 cm.
40 cm
56 cm
24 cm
Find
(i) the volume
(ii) the total surface area,
of the glass block.​

Answer 1

Answer:

I) volume= 53760cm

ii) TSA = 10897.56cm

Step-by-step explanation:

I) volume = length x width x height

volume= 56cm x 24 cm x 40cm

volume= 53760 cubic centimeters.

ii) TSA = 2(LW) +2(LH)+2(WH)

TSA= 2(56x24)+2(56x40)+2(24x40)

TSA= 9088 square centimeters. and you add the radius which is R= πxr2

πx24^2 = 10897.56 square centimeters.

I hope my answer is correct
